如何在 macOS Big Sur 11.4 中禁用校验和卸载？

将我的 macOS 更新到 macOS Big Sur 11.4 后，在我的主机和主机上的 VM 之间捕获的数据包显示 IP 和 TCP 层的数据包校验和错误。我已经在 VM 内部捕获了数据包，没有校验和错误。

我认为我尝试过：

  1. sysctl -w net.link.ether.inet.apple_hwcksum_rx=0并且sysctl -w net.link.ether.inet.apple_hwcksum_tx=0。我收到错误sysctl: unknown oid 'net.link.ether.inet.apple_hwcksum_rx'。我检查了一下，net.link.ether.inet 可用的选项有
~: sysctl -w net.link.ether.inet.
arp_llreach_base         maxhold                  send_conflicting_probes
arp_unicast_lim          maxhold_total            sendllconflict
host_down_time           maxtries                 stats
keep_announcements       probe_intvl              useloopback
log_arp_warnings         proxyall                 verbose
max_age                  prune_intvl

2.sudo ifconfig bridge100 -rxcsum -txcsum给予ifconfig: -rxcsum: Operation not supported on socket。

bridge100接口的相关信息：

答案1

正如@Spiff 建议的那样，我尝试了sudo sysctl net.link.generic.system.hwcksum_tx=0，sudo sysctl net.link.generic.system.hwcksum_rx=0并且它完成了工作。
