From 7252bc6ab55f64f1ee99a4e777e08a2bef970ac0 Mon Sep 17 00:00:00 2001 From: Micah Dowty Date: Wed, 23 Jul 2008 23:46:31 -0700 Subject: hdlcdrv: Fix CRC calculation. [ Upstream commit ae6134bdf3197206fba95563d755d2fa50d90ddd ] 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.
