# SRv6 support matrix data, rendered into support-matrix.md by hooks/support_matrix.py.
#
# Cell format:  <row id>: {s: yes|partial|no|unknown, r: "<first release>", note: "<short note>", src: <key or [keys]>}
# - A missing cell renders as "unknown".
# - Every yes / partial / no needs a source that states it. Unknown is better than a guess.
# - r is the first release a source documents. Leave it out when no source states one.
# - Sources are listed per platform under `sources:` and become footnotes on the page.
