Subject: Hardcode path to tcpdump as /usr/sbin/tcpdump.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=40a6fb4e18256fa778fb036dcacf2d7479ba6529;p=openvswitch

Hardcode path to tcpdump as /usr/sbin/tcpdump.

Otherwise it won't be found when run as non-root because such users
typically don't have /usr/sbin in $PATH.  (We use tcpdump in a fashion
that doesn't require root privilege.)
