tap speed argument is not working without generating any error.
This patch sets the configured speed during device start.

Hi,
The patch looks mainly ok to me.
I'll put some comments inline.

I think it would be best to also try setting the speed on the remote
(tap_ioctl(REMOTE_ONLY)), but continue execution even if that fails.

These includes are only useful inside rte_eth_tap.c, I would put them
there only.

Hi Pascal,
It looks like this ioctl fails to set tap speed. And as far as I can see speed
is hardcoded in kernel [1], do you know if it is possible to set speed of tap
interface?
Thanks,

Hi Ferruh,
I concur with you, it definitely looks like speed is hardcoded in the
kernel.
And there is no set_settings() callback defined either, so it won't be
possible to set anything using ethtool.
I haven't seen the error and I don't think Vipin Varghese sent a log for
that.
I'm still not sure what the patch was fixing; it would be good to have
that feedback to improve the patch.
Best regards,
Pascal
