After failing to verify configuration, it returns directly without
releasing link, which may cause memory leak.
Paolo Abeni thinks that the whole code of this driver is quite
"suboptimal" and looks unmainatained since at least ~15y, so he
suggests that we could simply remove the whole driver, please
take it into consideration.
Simon Horman suggests that the fix label should be set to
"Linux-2.6.12-rc2" considering that the problem has existed
since the driver was introduced and the commit above doesn't
seem to exist in net/net-next.

Unless I'm mistaken, this should be:
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")

I think that tags such as Reviewed-by need to be given explicitly.
And as the above two Reviewed-by tags were not, so it is a bit
odd for them to appear above.

Hi Semon,
Sorry about the naive mistakes made by Gan Gecen. Our team had
repeatedly talked about this issue and written it in our kernel
contribution guidance.
