Hi Jes,
No, It is clearly stated in the commit message :
"The FPGA is a bump-on-the-wire and thus affects operation of
the mlx5_core driver on the ConnectX ASIC."
Which means mlx5 FPGA user can only write logic which affects only
packets going in/out
A ConnectX chip - so it is only network stuff -.
We have this with other devices in the kernel where a primary device driver
provides an interface for an additional sub-driver to access another device
behind it. Like bt-coexist in some of the wifi drivers allowing access to a
bluetooth device behind it.
Blutooth over wifi or vise versa is a very good example to what you
are requesting.
But, it doesn't fit to what we are trying to do here. mlx5 FGPA is a
ConnectX card feature, not a new protocol.
In that case it would need to be an optional module that can be enabled
or disabled at build time.
Cheers,
Jes
