Subject: FW: ethtool patch to support bypass / fail-to-wire function

Dear Sir/Madam,

Per the below,
We have our bypass driver updated and we would like to move forward with integrating it into the kernel.
We think it need to be under drivers/net/

The description is per the below, taken from readme in linux.
The patch is attached,
Let me know how we can proceed with that. what should be the next step.

-------------
Theory of Operation:

The Silicom Bypass Network Interface Cards (NICs) are network cards with paired ports (2 or 4).
The pairs either act as a "wire" allowing the network packets to pass or insert the device in
between the two ports.  When paired with the on-board hardware watchdog or other failsafe,
they provide high availability for the network in the face of software outages or maintenance.

The software requirements are for a kernel level driver that interfaces with the bypass and watchdog,
as well as for control software. User control can be either the provided standalone executable
(/bin/bpctl) or the API exposed by the Silicom library.  
----------------------

Regards, David
