There is nothing to "do". If the chip offers the feature and the driver can take advantage of it, it will do so automatically. RX checksum support doesn't show up in hwfeatures. netstat -s will list the number of IP/TCP/UDP packets that were hardware checksummed. TX checksumming isn't enabled for em(4), because for complicated reasons it breaks with pf(4)'s rdr-to 127.0.0.1. -- Christian "naddy" Weisgerber [email protected]
