Subject[PATCH] drivers: net: xen-netfront: remove unused arrays
Date
This patch removes some unused arrays from the netfront
private data structure.
Also removes an unused address variable.

Signed-off-by: Vincenzo Maffione <v.maffione@gmail.com>

Hello,
I don't see the point in having those unused arrays in the private
structure.

Sorry if I'm missing something.

Cheers,
Vincenzo
