Unfortunately, yes, they do.  -rc4 and beyond requires firwmare version 
4.2 to fix some streaming mode->rdma mode connection transition fixes. 
And the interface between the driver and firmare changed which is why 
the requirement is there.  -rc4 and beyond _will not_ work with anything 
less than 4.2  I pushed the changes into -rc4 to get them in before 
ofed-1.2 ships as this was a critical bug.

The 4.2 firmware will be available this week from Chelsio.  Contact your 
chelsio rep to get it.  Perhaps you can get a pre-release version today...
