Subject: connmgr: Drop 'next_in_band_update' timer.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2bd5b8145b7cf1851d51e258ab614414f2496aae;p=openvswitch

connmgr: Drop 'next_in_band_update' timer.

This timer used to exist because it was possible for in-band remote IP
addresses to change without any intentional configuration change in one
case: where controller discovery found a new controller.  Controller
discovery was removed long ago, but the reason for the timer had been
forgotten and so remained.  This commit removes it.
