Subject: [net-next 04/13] net/mlx5: E-switch, Set per vport table default group number

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

Different per voprt table is created using a different per vport table
namespace. Because we can't use variable to set the namespace member
value.  If max group number is 0 in the namespace, use the eswitch
default max group number.
