* skge: changing MTU while running causes problemsStephen Hemminger2007-10-161-7/+44
| | | | | | | | Rather than bring network down/up when changing MTU, only need to impact receiver. Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* skge: fix ram buffer size calculationStephen Hemminger2007-10-161-27/+24
| | | | | | | | | | This fixes problems with transmit hangs on older fiber based SysKonnect boards. Adjust ram buffer sizing calculation to make it correct on all boards and make it like the code in sky2 driver.

* net: Fix new EMAC driver for NAPI changesBenjamin Herrenschmidt2007-10-161-8/+17
| | | | | | | | | | | | | | net: Fix new EMAC driver for NAPI changes This fixes the new EMAC driver for the NAPI updates. The previous patch by Roland Dreier (already applied) to do that doesn't actually work. This applies on top of it makes it work on my test Ebony machine. This patch depends on "net: Add __napi_sycnhronize() to sync with napi poll" posted previously.

* e1000e: don't poke PHY registers to retreive link statusAuke Kok2007-10-161-10/+21
| | | | | | | | | | | Apparently poking the link status registers when autonegotiation is running on the PHY might botch the PHY link on 80003es2lan devices. While this is a very rare condition we can completely avoid it alltogether by just using the MAC link bits to provide the proper information to ethtool.

* [netdrvr] forcedeth: improved probe info; dev_printk() cleanupsJeff Garzik2007-10-161-31/+57
| | | | | | | | | | | | | | | | | | | | | | | | main change: * greatly improve per-NIC probe diagnostic output. Similar to other net drivers, print out MAC address, PHY info, and various hardware and software flags that may be relevant. other changes: * similar to other net drivers, only print the initial version message when we have found at least one board. * don't bother to print error message when pci_enable_device() fails, it will do so for us. * use dev_printk() rather than printk() in nv_probe(). This gives use a standardized output similar to the rest of the kernel, and eliminates the need to manually print out PCI bus id. * use DRV_NAME constant where appropriate * clean struct pci_driver indentation Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

In the previous version, this logic was implemented using a combination of ebitmap_for_each_bit() and ebitmap_node_get_bit(), but is was worse in performance aspect. This logic is most frequestly used to compute a new AVC entry, so this patch can improve SELinux performance when AVC misses are happen. * struct ebitmap_node is redefined as an array of "unsigned long", to get suitable for using find_next_bit() which is fasted than iteration of shift and logical operation, and to maximize memory usage allocated from general purpose slab. * Any ebitmap_for_each_bit() are repleced by the new implementation in ss/service.c and ss/mls.c. Some of related implementation are changed, however, there is no incompatibility with the previous version. * The width of any new line are less or equal than 80-chars. The following benchmark shows the effect of this patch, when we access many files which have different security context one after another. The number is more than /selinux/avc/cache_threshold, so any access always causes AVC misses. selinux-2.6 selinux-2.6-ebitmap AVG: 22.763 [s] 8.750 [s] STD: 0.265 0.019 ------------------------------------------ 1st: 22.558 [s] 8.786 [s] 2nd: 22.458 [s] 8.750 [s] 3rd: 22.478 [s] 8.754 [s] 4th: 22.724 [s] 8.745 [s] 5th: 22.918 [s] 8.748 [s] 6th: 22.905 [s] 8.764 [s] 7th: 23.238 [s] 8.726 [s] 8th: 22.822 [s] 8.729 [s] Signed-off-by: KaiGai Kohei <kaigai@ak.jp.nec.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: James Morris <jmorris@namei.org>
