Subject: net/tap: fix interrupt vector array size
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=2ce7bc96344542f8d3e89b41bbaaafb12e1d9f72;p=dpdk.git

net/tap: fix interrupt vector array size

The size of the current interrupt vector array is fixed to an integer.

This patch will create an interrupt vector array based on the number
of rxqs.

Fixes: 4870a8cdd968 ("net/tap: support Rx interrupt")
