this is a replacement rather than a patch because the code needed to be reorganized to use select.

[Comment 2 erik quanstrom 2006-08-20 07:29:49 UTC]

the exact location of the initscripts hangis /lib/rcscripts/net/arping.sh:68

[...]
    68		if [[-x /sbin/arping ]] ; then
    69			foundmac=$(arping -c 2 -w "${w}" -D -f -I "${iface}" \
    70				"${ip}" 2>/dev/null \
    71				| sed -n 's/.*\[\([^]]*\)\].*/\U\1/p')
    72		elif [[ -x /usr/sbin/arping2 ]] ; then
[...]

in my case, w=3, iface=eth0, ip=192.168.0.4 where eth0 is

02:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)

using driver 8139too.o on 2.6.17-gentoo-r4.

I've mentioned this issue in the net-dev list.  That is probably where it should be addressed.
