Hello,
It seems CRC is not stripped out on 82599, neither on 82598.
The ixgbe driver is setting RDRXCTL for 82599, nothing else.
>From datasheet I found that RDRXCTL.CRCStrip and HLREG0.RXCRCSTRP
must be set to the same value.
I tested this patch (ixgbe-3.2.10) on 82598: always set IXGBE_HLREG0_RXCRCSTRP,
and it CRC is stripped now:
--- a/src/ixgbe_main.c
+++ b/src/ixgbe_main.c
@@ -3439,6 +3439,8 @@ static void ixgbe_set_rx_buffer_len(struct ixgbe_adapter
*adapter)
hlreg0 = IXGBE_READ_REG(hw, IXGBE_HLREG0);
/* set jumbo enable since MHADD.MFS is keeping size locked at max_frame
*/
hlreg0 |= IXGBE_HLREG0_JUMBOEN;
+ /* Enable CRC stripping */
+ hlreg0 |= IXGBE_HLREG0_RXCRCSTRP;
IXGBE_WRITE_REG(hw, IXGBE_HLREG0, hlreg0);
I'm going to test on 82599 too.
I can't test for other NIC than 82598 and 82599, may a test for (82598 ||
82599) should
be added.
Regards,
Jean-Mickael
