Subject: app/testpmd: fix removed device link status asking
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0da2a62bf9d72625fb5b779d9fd91e471ed2fb4a;p=dpdk.git

app/testpmd: fix removed device link status asking

In the RMV device event callback, there is a call for the removed
device stop operation which triggers a link status operation for the
removed device.

It may casue an error from the removed device PMD.

Skip the link status operation in the above described case.
