Subject: app/testpmd: limit port mask bits to configured maximum
X-Git-Tag: spdx-start~9932
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5e4937a088131272a15af3bac174d9b7e8567f91;p=dpdk.git

app/testpmd: limit port mask bits to configured maximum

The port mask parsing in testpmd allowed up to 64 bits to be processed,
even if RTE_MAX_ETHPORTS is set to a max of 32. Fix this by only
processing up to min(RTE_MAX_ETHPORTS,64) bits of the mask.
