Subject: stp: Increase hello time to 2 seconds.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a846b3519b004f95d2b3ab0aabd756f27f8c881d;p=openvswitch

stp: Increase hello time to 2 seconds.

An STP advertisement is sent after every expiry of the hello timer, so
this reduces STP advertisements to once every 2 seconds.

Once a second seemed like too often.

Suggested by Justin.
