[dpdk-dev] the default rule makes VF rep cannot get packets even if there is no offload rules

[贺鹏]

Hi, 

We found the patch "net/mlx5: revert default rules amount optimization", 
which installs a rule directing all egress traffic from VF to table 1, results in 
VF representors get no packets, even if there is no offload rules installed. 


I guess, if there is no rule indicating table 1, the table 1 does not exist, 
so all packets will be dropped? 

PF works just fine. 

We are using dpdk 19.11-rc3 for evaluation.
