Subject: net/iavf: fix endless loop
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=43b29221c1f13189f41d5200027a22f11149dfee;p=dpdk.git

net/iavf: fix endless loop

Change loop index from uint16_t to uint32_t since max
index 65535 could be exceeded when ring size is 2k+.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
