Subject: [net-next 2/4] bna: Fix Ucast Failure Handling
Date: Fri, 10 May 2013 10:02:15 -0700	[thread overview]
Message-ID: <1368205337-4624-3-git-send-email-rmody@brocade.com> (raw)
In-Reply-To: <1368205337-4624-1-git-send-email-rmody@brocade.com>

        Failure of the UCAST set for base mac address fails when user
        configures a duplicate mac address that matches that of another vNIC
        on the same port.
        The bna does not handle the ucast failure and keeps this address in
        cache. On disable of the vNIC, bna tries to delete the failed base mac
        address and the fw asserts.

        On failure of ucast address, mark ucast address set to false.
