It looks like it's padding it correctly then, so the IP header is 32-bit aligned. >> I don't get any warnings, so I assume 4B alignment is alright for >> MIPS. Is that right?

There's no point given that your IP headers are properly aligned thanks to the padding. Right now, it would probably decrease performance rather than increase it. If the two bytes of padding were missing then you'd need it. At least we know this *isn't* your problem... -- Robert Bradley _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
