re(4) incorrect checksum

[Pietro Cerutti]

Hi lists,

FreeBSD gahrtop.localhost 6.2-PRERELEASE FreeBSD 6.2-PRERELEASE #1:

re0: <RealTek 8168B/8111B PCIe Gigabit Ethernet> port 0xc800-0xc8ff
mem 0xff2ff000-0xff2fffff irq 17 at device 0.0 on pci2

($FreeBSD: src/sys/dev/re/if_re.c,v 1.46.2.20 2006/09/21 11:08:28 yongari Exp $)

I get checksum errors on every packet I send, example:

Checksum: 0x0bc5 [incorrect, should be 0x78fe (maybe caused by
checksum offloading?)]

I think this could be the cause of some web pages (e.g. Gmail in
standard view [html view works well]) not to be displayed.

I tracked down the problem to the re(4) driver just because wlan works good...

Any ideas?


Thanx,
