2.6.0-test3+sk98lin driver with hardware bug make eth unusable

[Ricardo Galli]

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?
