Subject: Use int type for setsockopt IP_TOS value
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eb0cb3161f52bfb8360e48af6a869ba3a5f06add;p=openvswitch

Use int type for setsockopt IP_TOS value

FreeBSD requires that setsockopt(..., IP_TOS, ...) be passed an int
value.  Linux accepts either int or char types (and has since at least
kernel 2.6.12) so just use int type unconditionally.
