Subject: habanalabs/gaudi: don't use nic_ports_mask in compute
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9081021029fd97d09056ed6ab13912339efab571;p=linux.git

habanalabs/gaudi: don't use nic_ports_mask in compute

nic_ports_mask is used by the networking part of the driver.
In the compute part, we use the HW_CAP bits to select what is active
and what is not.
