Subject: Make sure that do_port_input() always puts a MAC header on packets.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dac4f198616aad869063b1c77266e72d775e4aed;p=openvswitch

Make sure that do_port_input() always puts a MAC header on packets.

Prompted by persistent oopses on packets received by e1000e, in which
skb_mac_header() for the packet always returned null.
