Each tmnxBsxHttpPcyRdStatEntry contains statistics for
HTTP redirection.
An index with a valid tmnxBsxAaGrpPartIndex/tmnxBsxHttpRedirName
(an existing row in tmnxBsxHttpRedirTable), tmnxChassisIndex set
to one, and a zero value for each of tmnxBsxCardSlotNum and
tmnxMDASlotNum will return the summarized per group and HTTP
redirect name statistics.
