One idea is to separate or remove firmware part from both drivers
rathar than to delete those entire files from kernel package.
Look at drivers/net/tg3.c. If NETIF_F_TSO (see
include/linux/netdevice.h, offload implementation) is defined, then
such firmware parts are needed. So theoretically we can disable them
and remove firmware code with keeping driver code. One example of
diff (not compiled) is at:
I don't have tg3, so I don't know it works well (even it can be
compiled or not), but it's one way to fix without dropping entire
OTOH, unfortunatelly, firmware code of qla2xxx/* is coupled with
hardware initialization code. We need to have hardware specification
to know how to remove these parts.
I think it's also good idea that we contact to upstream author to
separate firmware from files and to make them work without any
firmware code. If you already thought/did, this mail is just my noise
about this issue.
In addition, I wonder this issue is really well-discussed, though.
Binary characters are marked as GPL by driver authors, so I still
think there is no problem to exist in linux kernel. To say radically,
removing firmware code from debian is just escape to think about linux
