Subject: 2.6.0-test3+sk98lin driver with hardware bug make eth unusable
Date: Tue, 12 Aug 2003 13:01:43 +0200 [thread overview]
Message-ID: <200308121301.43873.gallir@uib.es> (raw)
I've already reported this problem to syskonnect few weeks ago (without
success as I see).
There is a ASIC bug in several popular motherboards (including ASUS ones)
related to TX hardware checksum.
For packets smaller that 56 bytes (payload), as UDP dns queries, the asic
generates a bad checksum making the drivers unusable for "normal" Internet
usage:
12:50:26.602458 192.168.0.10.33520 > 192.168.0.3.53: [bad udp cksum 617e!]
55764+ [45727n] A? ponti.gallimedina.net. (39) (DF) (ttl 64, id 8705, len 67)
12:50:26.733664 192.168.0.10.33515 > 192.168.0.3.53: [bad udp cksum 5e7e!]...
12:50:40.603124 192.168.0.10.33520 > 192.168.0.3.53: [bad udp cksum 617e!]...
12:50:40.743436 192.168.0.10.33523 > 192.168.0.3.53: [bad udp cksum 607e!]...
12:50:54.604568 192.168.0.10.33526 > 192.168.0.3.53: [bad udp cksum 717e!]...
12:50:54.744493 192.168.0.10.33523 > 192.168.0.3.53: [bad udp cksum 607e!]...
The only solution is to comment out
#define USE_SK_TX_CHECKSUM
in skge.c
Could be this an option in Kconfig?
