Greetings (first post to the list)...
The following patch is required to allow bridging to occur on an
IBM x305 (1RU server). (It has been posted to the kernel-developers
mailing list previously.)
Background:
- The Dual Broadcom NICs in the IBM x305 have a broken checksum
routine which wants to calculate the checksum the ethernet
packet where the 'source' IP address is the IP address
of the sending interface.
This breaks bridging! (Upstream hosts see an invalid checksum
and drop the packet.)
- I have heard of other issues with Broadcom NICs not
working with IPv6 and broadcast/multicast which could be
related.
I would like to get these results and the fix verified, as it will
effect any hosts using this chipset. Does anyone have any pointers?
