[Intel-wired-lan] CMA alloc failed with 6 4-port X710 QAD4 NICs

[Ben Greear]

Hello,

I have a user trying to boot up our 4.20+ kernel with 6 4-port 10G NICs in it.

dmesg is full of cma_alloc errors.  I increased CMA space to 32MB, but still no luck.

Any idea how much CMA memory is needed for this config?

Thanks,
Ben
