Subject: [PATCH 03/12] dvb_net: check given MAC address, if invalid return -EADDRNOTAVAIL
Date: Fri, 24 Feb 2012 17:01:13 +0100 [thread overview]
Message-ID: <1330099282-4588-4-git-send-email-danny.kukawka@bisect.de> (raw)
In-Reply-To: <1330099282-4588-1-git-send-email-danny.kukawka@bisect.de>
Check if given address is valid in .ndo_set_mac_address, if
invalid return -EADDRNOTAVAIL as eth_mac_addr() already does
if is_valid_ether_addr() fails.
