[Xen-devel] [PATCH] drivers: net: xen-netfront: remove unused arrays

[Vincenzo Maffione <v.maffione@xxxxxxxxx>]

This patch removes some unused arrays from the netfront
private data structure.
Also removes an unused address variable.

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

Sorry if I'm missing something.

Cheers,
  Vincenzo
