It seems somethin= g is wrong when using the interface i40evf_dev_stats_get to get bytes statistics. 1. When using vfs from two pfs for tx/rx, the bytes statistics is correct. 2. When using two vfs of the same pf for tx/rx, the rx bytes statistics is losing 4 bytes per packet. I have checked mbufs in the rx funcation, and the pkt_len is corrent in both scenes. Seems it's related to CRC Strip, but needs further confirmation. --=20 You are receiving this mail because: You are the assignee for the bug.=
