    ktls: Propagate EPG_FLAG_ANON to mapped mbufs

    Otherwise ktls_mbuf_crypto_state() will reject mbufs created by
    _mb_unmapped_to_ext(), which arises when transmitting packets through an
    interface that doesn't support unmapped mbufs, and the loopback
    interface in particular.

    Fixes:          3444414cb463 ("ktls: Don't attempt to modify non-anonym=
ous
mbufs on the receive path")
