[dpdk-dev] [PATCH 1/7] bus/vmbus: fix secondary process setup

[Stephen Hemminger]

From: Stephen Hemminger <sthemmin at microsoft.com>

The secondary process doesn't correctly map the second
and later resources because it doesn't change the offset.

Fixes: 831dba47bd36 ("bus/vmbus: add Hyper-V virtual bus support")
