[LTP] [PATCH 2/2] network/busy_poll: Remove unnecessary driver check

[Petr Vorel]

Hi Martin,

> Kernel v4.5 extended the busy_poll functionality to all network drivers.
> Limiting the test only to drivers which implemented busy_poll as internal
> feature on older kernels does not make sense.

Ah, you mean 85c72ba1ed0c ("Merge branch 'net-generic-busy-polling'")
Good catch, thx!!

Fixes: ead28f929 ("busy_poll: skip busy_poll flag test on kernels 4.5+")

Kind regards,
Petr
