Subject: [PATCH] dvb_net endianness fix
Date: Sun, 22 Jun 2008 15:20:49 +0100 [thread overview]
Message-ID: <E1KAQQz-00024e-JS@ZenIV.linux.org.uk> (raw)
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.
