Subject: ofproto-dpif: Add tests for VLAN handling.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=04c956fc029bb97de17b62cb6d243b50f0bc9f58;p=openvswitch

ofproto-dpif: Add tests for VLAN handling.

These tests would have caught the bug fixed in the previous commit
"ofproto-dpif: Fix behavior when a subset of VLANs is trunked."
