Subject: [PATCH] usbnet: allow mini-drivers to consume L2 headers
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8
|
|
Content-Transfer-Encoding: 8bit
|

|
|
Assume the minidriver has taken care of all L2 header parsing
|
|
if it sets skb->protocol. This allows the minidriver to
|
|
support non-ethernet L2 headers, and even operate without
|
|
any L2 header at all.
