Re: [PATCH 04/10] GRETH: added greth_compat_mode module parameter

From: Daniel Hellstrom <redacted>

The greth_compat_mode option can be used to set a GRETH GBit capable MAC
in operate as if the GRETH 10/100 device was found. The GRETH GBit supports
TCP/UDP checksum offloading, unaligned frame buffers, scatter gather etc.
Enabling this mode allows the developer to test the GRETH 10/100 device
without all features mentioned above on a GBit MAC capable of the above.

No special device specific module parameters please.

What if every single driver author added something like this and they
all named it something different or made it behave in slightly differing
ways?

What kind of user experience would that result in?

It would result in a sucky one, which is why we avoid adding all kinds
of hacky driver specific module options.

Find a generic way to provide this functionality.
