Subject: [PATCH 2/4] Staging: hv: Remove typedef NETVSC_PACKET and PNETVSC_PACKET


typedef NETVSC_PACKET and PNETVSC_PACKET are removed and their usages
are replace by the use of struct hv_netvsc_packet and
struct hv_netvsc_packet * respectively.

Here is the semantic patch generated to perform this transformation:
(http://coccinelle.lip6.fr/)
