net/mlx5: Fix lowest FDB pool size
|
|
|
|
The pool sizes represent the pool sizes in the fw. when we request
|
|
a pool size from fw, it will return the next possible group.
|
|
We track how many pools the fw has left and start requesting groups
|
|
from the big to the small.
|
|
When we start request 4k group, which doesn't exists in fw, fw
|
|
wants to allocate the next possible size, 64k, but will fail since
|
|
its exhausted. The correct smallest pool size in fw is 128 and not 4k.
|
