[dpdk-dev] [PATCH v2] eal: Allow combining -m and --no-huge

[Simon Kagstrom <simon.kagstrom@netinsight.net>]

Needed to run as non-root but with higher memory allocations, and
removes a constraint on no-huge mode being limited to 64M. A usage
example is if running with file input with the pcap PMD, which can be
done as non-root after this patch via e.g.,

    ./test-dpdk --no-huge -m 1024 -l 0,1 -n3 --vdev 'eth_pcap0,rx_pcap=/tmp/eth-rx.pcap,tx_pcap=/tmp/eth-tx.pcap'
