[asterisk-commits] russell: branch 1.8 r353175 - /branches/1.8/main/netsock.c

[SVN commits to the Asterisk project]

Author: russell
Date: Sat Jan 28 20:42:59 2012
New Revision: 353175

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=353175
Log:
Find even more network interfaces.

The previous change made the code look for emN and pciN in addition to what
it did originally, which was search for ethN.  However, it needed to be looking
for pciN#N, so that's what it does now.

This also moves the memset() to be before every ioctl().
