Subject: [PATCH 291/297] 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.
|
|
|
|
