From ae6134bdf3197206fba95563d755d2fa50d90ddd Mon Sep 17 00:00:00 2001 From: Micah Dowty Date: Mon, 21 Jul 2008 09:59:09 -0700 Subject: 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.
