Merge branch 'bnx2x'
Yuval Mintz says: ==================== This patch series contains several enhancements, as well as small fixes: - Patch [1/5] - Prevent a theoretical problem in our GRO implementation. - Patch [2/5] - Support Rx/Tx pause control configuration in autoneg. - Patch [3/5] - Enhance support for VF's MAC setting and removal. - Patch [4/5] - Fix a small memory leak between bnx2x and cnic. - Patch [5/5] - Allow bnx2x to recover after a second slot reset. Please consider applying these patches to `net-next'. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
