net/mlx4_core: Enable 4K UAR if SRIOV module parameter is not enabled

2017-08-30T08:21:42Z

[ Upstream commit ca3d89a3ebe79367bd41b6b8ba37664478ae2dba ] enable_4k_uar module parameter was added in patch cited below to address the backward compatibility issue in SRIOV when the VM has system's PAGE_SIZE uar implementation and the Hypervisor has 4k uar implementation. The above compatibility issue does not exist in the non SRIOV case. In this patch, we always enable 4k uar implementation if SRIOV is not enabled on mlx4's supported cards.

nfp: fix infinite loop on umapping cleanup

[ Upstream commit eac2c68d663effb077210218788952b5a0c1f60e ] The while loop that performs the dma page unmapping never decrements index counter f and hence loops forever.

net/mlx4_en: don't set CHECKSUM_COMPLETE on SCTP packets

2017-08-13T02:31:22Z

[ Upstream commit e718fe450e616227b74d27a233cdf37b4df0c82b ] if the NIC fails to validate the checksum on TCP/UDP, and validation of IP checksum is successful, the driver subtracts the pseudo-header checksum from the value obtained by the hardware and sets CHECKSUM_COMPLETE. Don't do that if protocol is IPPROTO_SCTP, otherwise CRC32c validation fails.

net/mlx5: E-Switch, Re-enable RoCE on mode change only after FDB destroy

2017-08-11T15:49:36Z

[ Upstream commit 5bae8c031053c69b4aa74b7f1ba15d4ec8426208 ] We must re-enable RoCE on the e-switch management port (PF) only after destroying the FDB in its switchdev/offloaded mode. Otherwise, when encapsulation is supported, this re-enablement will fail. Also, it's more natural and symmetric to disable RoCE on the PF before we create the FDB under switchdev mode, so do that as well and revert if getting into error during the mode change later.

tg3: Fix race condition in tg3_get_stats64().

2017-08-11T15:49:34Z

[ Upstream commit f5992b72ebe0dde488fa8f706b887194020c66fc ] The driver's ndo_get_stats64() method is not always called under RTNL. So it can race with driver close or ethtool reconfigurations. Fix the race condition by taking tp->lock spinlock in tg3_free_consistent() when freeing the tp->hw_stats memory block. tg3_get_stats64() is already taking tp->lock.
