Subject: [PATCH] NetRxPkt: Account buffer with ETH header in IOV length
|
|
|
|
|
|
|
|
In case of VLAN stripping ETH header is stored in a
|
|
|
|
separate chunk and length of IOV should take this into
|
|
|
|
account.
|
|
|
|
|
|
|
|
This patch fixes checksum validation for RX packets
|
|
|
|
with VLAN header.
|
|
|
|
|
|
|
|
Devices affected by this problem: e1000e and vmxnet3.
