Subject: Move Solaris if_fd to local scope.
X-Git-Tag: release-1.1pre11~106
X-Git-Url: https://www.tinc-vpn.org/git/browse?a=commitdiff_plain;h=638260865399693c3ced9337ef2664c5ba968a2a;p=tinc

Move Solaris if_fd to local scope.

This variable is never used outside of setup_device(), therefore there is no
reason to declare it in global scope.
