X-Git-Tag: firefly_0821_release~176^2~755^2~39
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=aa744cc01fe0f21dfbe2744d3fd5f2fb3244c9b3;p=firefly-linux-kernel-4.4.55.git

IB/core: Remove smac and vlan id from qp_attr and ah_attr

Smac and vlan id could be resolved from the GID attribute, and thus
these attributes aren't needed anymore. Removing them.
