-Subject: [PATCH 5/9] net: lan78xx: Allow for VLAN headers in timeout.
-
-The frame abort timeout being set by lan78xx_set_rx_max_frame_length
-didn't account for any VLAN headers, resulting in very low
-throughput if used with tagged VLANs.
-Use VLAN_ETH_HLEN instead of ETH_HLEN to correct for this.

-Subject: [PATCH 6/9] net: lan78xx: Request s/w csum check on VLAN tagged
- packets.
-
-There appears to be some issue in the LAN78xx where the checksum
-computed on a VLAN tagged packet is incorrect, or at least not
-in the form that the kernel is after. This is most easily shown
-by pinging a device via a VLAN tagged interface and it will dump
-out the error message and stack trace from netdev_rx_csum_fault.
-It has also been seen with standard TCP and UDP packets.
-
-Until this is fully understood, request that the network stack
-computes the checksum on packets signalled as having a VLAN tag
-applied.
