sys/dev/cxgbe/cxgbei/icl_cxgbei.c
854	I'm just not sure what header this would go in. It seems like something that would perhaps belong in a common t4_foo.h header?
865–867	When I tried this setting, it didn't work, so possibly I should just drop this comment.

sys/dev/cxgbe/cxgbei/icl_cxgbei.c
854	I've renamed this to `CXGBEI_MAX_ISO_PAYLOAD` and moved it to cxgbei.h.
865–867	When I tried this setting, it didn't work, so possibly I should just drop this comment. We've since had to debug an issue with this particular value internally and I've changed the expression that goes here. I'll update this patch when the updated version when it's ready.

Some cleanups to PLEN_MAX.
Add a knob to disable ISO.
Disable ISO on T4.
