IB/core: Clear AH attr variable to prevent garbage data
During create-ah from userspace, uverbs is sending garbage data in attr.dmac and attr.vlan_id. This patch sets attr.dmac and attr.vlan_id to zero. Fixes: dd5f03beb4f7 ("IB/core: Ethernet L2 attributes in verbs/cm structures") Signed-off-by: Devesh Sharma <devesh.sharma@emulex.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
