Eitan,

Isn't the 2K MTU issue with Tavor comes into play only under RC QP? more 
over, doing TAVOR/UD/2K MTU is very common, eg IPoIB.

So does your patch relies on a somehow completing quirk in the host side 
for UD based ULPs to add some mtu selector which will prevent the SM 
side quirk to take action?

Or.
