Subject: [PATCH net-next 01/11] net/mlx5: E-Switch, Increase max int port number for offload

From: Chris Mi <cmi@...dia.com>

Currently MLX5E_TC_MAX_INT_PORT_NUM is 8. Usually int port has one
ingress and one egress rules. But sometimes, a temporary rule can be
offloaded as well, eg:

recirc_id(0),in_port(br-phy),eth(src=10:70:fd:87:57:c0,dst=33:33:00:00:00:16),
	eth_type(0x86dd),ipv6(frag=no), packets:2, bytes:180, used:0.060s,
	actions:enp8s0f0

If one int port device offloads 3 rules, only 2 devices can offload.
Other devices will hit the limit and fail to offload. Actually it is
insufficient for customers. So increase the number to 32.
