From 6934d33556b366d22392a415ca09d720fed6a442 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Tue, 7 Dec 2010 22:21:52 +0000 Subject: [PATCH] hso: IP checksuming doesn't work on GE0301 option cards There is definitly a problem, that some option cards send up broken IP pakets leading to corrupted IP packets. These corruptions aren't detected, because the driver claims that the packets are already checksummed. This change removes the CHECKSUM_UNNECESSARY option and let IP detect broken data.
