Subject: V4L/DVB (8126): net endianness fix
X-Git-Tag: v2.6.27-rc1~966^2~188
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f51b10ef6520f2bd725dc333e771eabd55d6c04f;p=linux-2.6

V4L/DVB (8126): net endianness fix

According to RFC 4326 (4.1) D-bit is MSB in net-endian 16bit.
dvb_net.c did
				/* Set D-bit for CRC32 verification,
				 * if it was set originally. */
				ulen |= 0x0080;
which works of little-endian (htons(1<<15) is 0x0080 there), but breaks
on big-endian.
