What impact will that have on performance? See https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252981 Basically, some hardware offload drivers don't work correctly with ZFS, and the opencrypto shims in ZFS don't work properly with hardware offload drivers. For 13.0 the best solution is to just disable that support. Note that this doesn't apply to software-accelerated crypto drivers like aesni(4).
