This is a note to let you know that I've just added the patch titled bnxt_re: changing the ip address shouldn't affect new connections to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: bnxt_re-changing-the-ip-address-shouldn-t-affect-new-connections.patch and it can be found in the queue-4.14 subdirectory.

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().
