[dpdk-dev] [PATCH] netvsc: update link info when getting device info

[Mohammed Gamal <mgamal@redhat.com>]

testpmd 'show summary' command always shows interface status as down
with 0 Mbps speed regardless of the underlying VF's status.
This happens as hn_dev_link_update() is never called, even on the initial
RNDIS_STATUS_MEDIA_CONNECT message as LSC interrupts are not yet enabled
at this point.

Let's call it and update link info when calling hn_dev_info_get().
