[PATCH] net: ethernet: cavium: Correct Cacivum Thunderx nicvf/nicpf modules names

[PATCH] net: ethernet: cavium: Correct Cacivum Thunderx nicvf/nicpf modules names

[Vadim Lomovtsev]

From: Vadim Lomovtsev <Vadim.Lomovtsev@cavium.com>

It was found that ethtool provides unexisting module name while
it queries the specified network device for associated driver
information.

This patch is to correct Cavium CN88xx Thunder nicvf/nicpf modules
names 'nicvf' to 'thunder_nicvf' and 'nicpf' to 'thunder_nicpf'.

Self NACK to this one, subject line typo, sorry.

Re: [PATCH v2] net: ethernet: cavium: Correct Cavium Thunderx nicvf/nicpf modules names

[Vadim Lomovtsev]

Self NACK here: modules names has to contain dashes instead
of underscores, as it defined at sources (or update modules
DRV_NAME definitions whithin the source files with underscores).
Shame on me.

[PATCH v3] net: ethernet: cavium: Correct Cavium Thunderx NIC module and driver names

[Vadim Lomovtsev]

From: Vadim Lomovtsev <Vadim.Lomovtsev@cavium.com>

It was found that ethtool provides unexisting module name while
it queries the specified network device for associated driver
information. Then user tries to unload that module by provided
module name and fails.

This happens because ethtool reads value of DRV_NAME macro,
while module name is defined at the driver's Makefile.

This patch is to correct Cavium CN88xx Thunder NIC driver modules
names 'nicvf' to 'thunder_nicvf' and 'nicpf' to 'thunder_nicpf' along
with updating DRV_NAME macro values accordingly.

Once your driver has been deployed in a real upstream release you
should never change the driver module name.

So if you want to fix things, you'll have to fix them the other
way around, by not changing the module name but changing the
strings that ethtool ends up with instead.

Thank you.

[PATCH v4] net: ethernet: cavium: Correct Cavium Thunderx NIC driver names accordingly to module name

[Vadim Lomovtsev]

From: Vadim Lomovtsev <Vadim.Lomovtsev@cavium.com>

It was found that ethtool provides unexisting module name while

information. Then user tries to unload that module by provided
module name and fails.

This happens because ethtool reads value of DRV_NAME macro,
while module name is defined at the driver's Makefile.

This patch is to correct Cavium CN88xx Thunder NIC driver names
(DRV_NAME macro) 'thunder-nicvf' to 'nicvf' and 'thunder-nic'
to 'nicpf', sync bgx and xcv driver names accordingly to their
module names.
