虚拟机之间跨主机使用tcp连接不通，报文进入虚拟机后，checksum校验不通过，被丢弃。虚拟机采用的是物理网卡的checksum校验功能。在宿主机上关闭checksum校验ethtool-K ethx tx off，tcp能连通，但是小包pps下降严重，需要提供支持打开checksum的openEuler博通驱动 环境信息: 网卡厂商+网卡型号（芯片型号）：Broadcom P210tep NetXtreme-E Dual-port 10GBASE-T Ethernet PCIe Adapter 网卡驱动版本：bnxt_en 5.10.0-182.0.0.95.r3008_242_331 网卡固件版本：233.1.135.7
