From b90b2b853411953e4ec7b79420816dc994abc8d1 Mon Sep 17 00:00:00 2001 From: Micah Dowty Date: Mon, 21 Jul 2008 09:59:09 -0700 Subject: [PATCH] hdlcdrv: Fix CRC calculation. This is a trivial patch against the hdlcdrv module that fixes its CRC calculation. The finished CRC was overwriting the first two bytes of each packet rather than being appended to the end. I've tested this with 2.6.8 and 2.6.10-rc1, but hdlcdrv hasn't changed much recently so it should work with many other kernel versions.
