Subject: bnxt_re: changing the ip address shouldn't affect new connections
From: Sriharsha Basavapatna <sriharsha.basavapatna@xxxxxxxxxxxx>
[ Upstream commit 063fb5bd1a01937094f40169a20e4aa5ca030db1 ]
While adding a new gid, the driver currently does not return the context
back to the stack. A subsequent del_gid() (e.g, when ip address is changed)
doesn't find the right context in the driver and it ends up dropping that
request. This results in the HW caching a stale gid entry and traffic fails
because of that. Fix by returning the proper context in bnxt_re_add_gid().
