| | | | | | | | | | The driver currently ignores the local or remote link faults raised at the mac layer. This patch fixes it.

* | cxgb3: Replace LRO with GROHerbert Xu2009-01-211-38/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes cxgb3 invoke the GRO hooks instead of LRO. As GRO has a compatible external interface to LRO this is a very straightforward replacement. I've kept the ioctl controls for per-queue LRO switches. However, we should not encourage anyone to use these. Because of that, I've also kept the skb construction code in cxgb3. Hopefully we can phase out those per-queue switches and then kill this too.

* cxgb3: Keep LRO off if disabled when interface is downRoland Dreier2009-01-111-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | I have a system with a Chelsio adapter (driven by cxgb3) whose ports are part of a Linux bridge. Recently I updated the kernel and discovered that things stopped working because cxgb3 was doing LRO on packets that were passed into the bridge code for forwarding. (Incidentally, this problem manifested itself in a strange way that made debugging a bit interesting -- for some reason, the skb_warn_if_lro() check in bridge didn't trigger and these LROed packets were forwarded out a forcedeth interface, and caused the forcedeth transmit path to get stuck) This is because cxgb3 has no way of keeping state for the LRO flag until the interface is brought up, so if the bridging code disables LRO while the interface is down, then cxgb3_up() will just reenable LRO, and on my Debian system at least, the init scripts add interfaces to a bridge before bringing the interfaces up. Fix this by keeping track of each interface's LRO state in cxgb3 so that when bridge disables LRO, it stays disabled in cxgb3_up() when the interface is brought up. I did this by changing the rx_csum_offload flag into a pair of bit flags; the effect of this on the rx_eth() fast path is miniscule enough that it should be fine (eg on x86, a cmpb instruction becomes a testb instruction).

| * RDMA/cxgb3: deadlock in iw_cxgb3 can cause hang when configuring interface.Steve Wise2008-11-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the iw_cxgb3 module's cxgb3_client "add" func gets called by the cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo function in cxgb3 to get the fw version and other info. Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.
