Hi

By default bad CRC packets are dropped and raise the ierror counter.

Is there a way to change this behavior for I350 (igb) and rx it by the app?

I've tried setting DEV_RX_OFFLOAD_KEEP_CRC but this doesn't help (I think this only \
keeps CRC for good packets) I've also tried enabling the Store Bad Packet (not sure \
what it does but it's the closet I could find) by setting in e1000/igb_rxtx.c rctl |= \
E1000_RCTL_SBP;  E1000_WRITE_REG(hw, E1000_RCTL, rctl); Didn't help either.

Is it possible to do with I350?
Or with any of the other intel NICs? X522 (ixgbe) or X710 (i40e)?

Thanx,

  *   Ido
