| * drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker2015-06-231-11/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread. No code is changed in this commit, just Kconfig help text. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>

After copying the data in the header buffer (which can be just the header if split header processing succeeded for header plus data if split header processing did not succeed) into the SKB, check for remaining data in the receive buffer. If there is data remaining in the receive buffer, add that as a frag to the SKB. Once an SKB has been allocated, all other descriptors are added as frags to the SKB.

The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
| * net: ethernet: pcnet32: Setup the SRAM and NOUFLO on Am79C97{3, 5}Markos Chandras2015-03-201-2/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a MIPS Malta board, tons of fifo underflow errors have been observed when using u-boot as bootloader instead of YAMON. The reason for that is that YAMON used to set the pcnet device to SRAM mode but u-boot does not. As a result, the default Tx threshold (64 bytes) is now too small to keep the fifo relatively used and it can result to Tx fifo underflow errors. As a result of which, it's best to setup the SRAM on supported controllers so we can always use the NOUFLO bit.

| | | | | | | | | | | | | | | | | | | | | | | | The Rx coalescing value is internally converted from usecs to a value that the hardware can use. When reporting the Rx coalescing value, this internal value is converted back to usecs. During the conversion from and back to usecs some rounding occurs. So, for example, when setting an Rx usec of 30, it will be reported as 29. Fix this reporting issue by keeping the original usec value and using that during reporting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Tx coalescing support in the driver was a software implementation for something lacking in the hardware. Using hrtimers, the idea was to trigger a timer interrupt after having queued a packet for transmit. Unfortunately, as the timer value was lowered, the timer expired before the hardware actually did the transmit and so it was racey and resulted in unnecessary interrupts. Remove the Tx coalescing support and hrtimer and replace with a Tx timer that is used as a reclaim timer in case of inactivity.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that the hardware may not have been properly shutdown before this driver gets control, through use by firmware, for example. Until the driver is loaded, interrupts associated with the hardware could go pending. When the IRQs are requested napi support has not been initialized yet, but the ISR will get control and schedule napi processing resulting in a kernel panic because the poll routine has not been set. Adjust the code so that the driver is fully ready to handle and process interrupts as soon as the IRQs are requested. This involves requesting and freeing IRQs during start and stop processing and ordering the napi add and delete calls appropriately. Also adjust the powerup and powerdown routines to match the start and stop routines in regards to the ordering of tasks, including napi related calls.

[ The "crypto: switch af_alg_make_sg() to iov_iter" commit was wrong, and this pull actually adds an extra commit on top of the branch I'm pulling to fix that up, so that the pre-merge state is ok. - Linus ] 2) Various optimizations to the ipv4 forwarding information base trie lookup implementation. From Alexander Duyck. 3) Remove sock_iocb altogether, from CHristoph Hellwig. 4) Allow congestion control algorithm selection via routing metrics. From Daniel Borkmann. 5) Make ipv4 uncached route list per-cpu, from Eric Dumazet. 6) Handle rfs hash collisions more gracefully, also from Eric Dumazet. 7) Add xmit_more support to r8169, e1000, and e1000e drivers. From Florian Westphal. 8) Transparent Ethernet Bridging support for GRO, from Jesse Gross. 9) Add BPF packet actions to packet scheduler, from Jiri Pirko. 10) Add support for uniqu flow IDs to openvswitch, from Joe Stringer. 11) New NetCP ethernet driver, from Muralidharan Karicheri and Wingman Kwok. 12) More sanely handle out-of-window dupacks, which can result in serious ACK storms. From Neal Cardwell. 13) Various rhashtable bug fixes and enhancements, from Herbert Xu, Patrick McHardy, and Thomas Graf. 14) Support xmit_more in be2net, from Sathya Perla. 15) Group Policy extensions for vxlan, from Thomas Graf. 16) Remove Checksum Offload support for vxlan, from Tom Herbert. 17) Like ipv4, support lockless transmit over ipv6 UDP sockets.

| | * amd-xgbe: Check per channel DMA interrupt use in main ISRLendacky, Thomas2015-02-071-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using per channel DMA interrupts the transmit interrupt (TI) and the receive interrupt (RI) are masked off so as to not generate an interrupt to the main ISR. However, should another interrupt fire for the DMA channel that is handled by the main ISR the TI/RI bits can still be set. This will cause the wrong and uninitialized napi structure to be used causing a panic. Add a check to be sure per channel DMA interrupts are not enabled before acting on those bit flags.

In the include/linux/if_vlan.h case, the type used for a local variable was changed in 'net', whereas the function got rewritten to fix a stacked vlan bug in 'net-next'. In drivers/vhost/net.c, Al Viro's iov_iter conversions in 'net-next' overlapped with an endainness fix for VHOST 1.0 in 'net'. In drivers/net/vxlan.c, vxlan_find_vni() added a 'flags' parameter in 'net-next' whereas in 'net' there was a bug fix to pass in the correct network namespace pointer in calls to this function.

| * | | mii: Handle link state changes for forced modes in mii_check_media()Ben Hutchings2015-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mii_check_media() does not update the link (carrier) state or log link changes when the link mode is forced. Drivers using the mii library must do this themselves, but most of them do not. Instead of changing them all, provide a sensible default behaviour similar to mii_check_link() when the mode is forced. via-rhine depends on it being a no-op in this case, so make its call to mii_check_media() conditional.

| * | | amd-xgbe-phy: Change auto-negotiation logicLendacky, Thomas2015-01-161-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The auto negotiation logic was geared to being the initiator of the auto negotiation. This presented problems when auto negotiation was initiated by the remote end. Change the auto negotiation logic to make use of the auto negotiation event interrupt thus allowing the auto negotiation state machine to function properly in either scenario. This also removes the polling during auto-negotiation. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | | amd-xgbe: Remove need for Tx path spinlockLendacky, Thomas2015-01-162-28/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the Tx ring cleanup can run at the same time that data is being transmitted, a spin lock was used to protect the ring. This patch eliminates the need for Tx spinlocks by updating the current ring position only after all ownership bits for data being transmitted have been set. This will insure that ring operations in the Tx cleanup path do not interfere with the ring operations in the Tx transmit path.
