Miller <davem@xxxxxxxxxxxxx> Date: Wed Mar 12 15:57:26 2014 -0400 Merge branch 'mlx4-next' Or Gerlitz says: ==================== mlx4: Add SRIOV support for RoCE This series adds SRIOV support for RoCE (RDMA over Ethernet) to the mlx4 driver. The patches are against net-next, as of commit 2d8d40a "pkt_sched: fq: do not hold qdisc lock while allocating memory" changes from V1: - addressed feedback from Dave on patch #3 and changed get_real_sgid_index() to be called fill_in_real_sgid_index() and be a void function. - removed some checkpatch warnings on long lines changes from V0: - always check the return code of mlx4_get_roce_gid_from_slave(). The call we fixed is introduced in patch #1 and later removed by patch #3 that allows guests to have multiple GIDS. The 1..3 separation was done for proper division of patches to logical changes. ==================== Signed-off-by: David S.
