[E1000-devel] [PATCH 6/7] NET: Squelch compiler warning in net_generic()

[Chuck L. <chu...@or...>]

include/net/netns/generic.h: In function ‘net_generic’:
include/net/netns/generic.h:40:2: warning: comparison between signed
		and unsigned integer expressions [-Wsign-compare]

Seen with gcc (GCC) 4.6.3 20120306 (Red Hat 4.6.3-2).

Ensure everywhere that stores or compares a net ID uses a signed int.

Signed-off-by: Chuck Lever <chu...@or...>
