chg: usr: Add missing EDNS option mnemonics
The Report-Channel
and ZONEVERSION
EDNS options can now be sent using dig +ednsopt=report-channel
(or dig +ednsopt=rc
for short), and dig +ednsopt=zoneversion
.
Several other EDNS option names, including DAU
, DHU
, N3U
, and CHAIN
, are now displayed correctly in text and YAML formats. Also, an inconsistency has been corrected: the TCP-KEEPALIVE
option is now spelled with a hyphen in both text and YAML formats; previously, text format used a space.
