Hi,
I have a Virtual setup with an Intel 82599 NIC (VF).
I'm trying to Disable CRC stripping, and the flag is gracefully ignored.
This seems to be documented In the DPDK June Release notes (6.16).
Are these limitations (Jumbo Frames, CRC Stripping , Checksum ) are a NIC
(HW/FW)limitations? Or is this something that can be resolved in SW to
allow separate per VF configuration?
Thanks.

Hi Alex
For 82599, it is controlled by a register to globally enable or disable that. This can only done in PF side, it is not reasonable to do that in VF.
In addition, i40e or else might be different.

Helin
