:This is depressing.

:The Dell PowerEdge 2550's use the BGE driver (Tigon III). I'm really
:surprised that the problem exists on the Tigon III. My personal
:experience with Tigon III's was that the hardware checksumming was
:working. Maybe my testing was too lax. 8-(.
Yup. Of course I am completely Jaded now after listening to B.P.
curse the chipset while he was debugging it :-)
:My local copy of the -STABLE source tree leaves BGE_CSUM_FEATURES set
:on in the driver; is there a change that needs to be MFC'ed to turn
:these suckers off?
:...
:There's no similar comment in the if_bge.c ...
:
Well, that entire section of code is #if 0'd out in -stable's
BGE driver (/usr/src/sys/dev/bge/if_bge.c line 1981). The
comment reads:
#if 0 /* currently broken for some packets, possibly related to TCP options */
So even with BGE_CSUM_FEATURES set, it should all be turned off now.
This change was made on 14-December-01 by DG. Anyone with an earlier
driver may be running with checksums enabled.
:Can you guys elaborate on the problem? Was it on incoming checksums,
:outgoing checksums, or both?
:...
:Thanks,
:-- Terry
It was on incoming checksums I believe.
