Subject: brcompat: Remove requirement that that no datapaths exist at load time.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6dac2b9ed9d77a92f53258f694117fa8b989aacb;p=openvswitch

brcompat: Remove requirement that that no datapaths exist at load time.

We previously required that brcompat_mod be loaded before any datapaths
were created, because creation and destruction of datapaths and ports
differed when brcompat_mod was loaded, but the latter is no longer the
case so there is no reason for the former anymore.
