UIO驅動

uio_pci_generic

啟動參數配置，需要配置到grub中，重啟生效。

# cat /proc/cmdline BOOT_IMAGE=/vmlinuz-4.15.0-112-generic root=/dev/mapper/ubuntu--vg-ubuntu--lv ro console=tty0 console=ttyS0,115200n8 isolcpus=1-3 rcu_nocbs=1-3 nohz_full=1-3 hugepagesz=1GB hugepages=4 default_hugepagesz=1GB maybe-ubiquity

結果
RFC2544測試，64字節報文，雙向大約能達到線速的75%。

網卡X710

開始VPP沒有加載上X710網卡。
