Since ehca can support 4K MTU, we would like to see a patch
in IPoIB to allow link MTU to be up to 4K instead of current 2K for
2.6.24 kernel. The idea is IPoIB link MTU will pick up a return value
from SM's default broadcast MTU. This patch should be a small patch,
I hope you are OK with this.
The only IB switching chip I know does not support 4K IB MTU so you
would be able to use it only in p2p connections, correct?
Or.
ConnectX can support 4K MTU too (need a configured ini file)
Anafa II switch can support 4K MTU with a special configuration.
