Each tmnxBsxHttpRdStatEntry contains statistics for
HTTP error redirection.
An index with a valid tmnxBsxAaGrpPartIndex, tmnxBsxHttpRedirErrName,
tmnxBsxHttpRedirErrCode (an existing row in
tmnxBsxHttpRedirErrCodeTable), tmnxChassisIndex set to one,
and a zero value for each of tmnxBsxCardSlotNum and tmnxMDASlotNum
will return the summarized per group and HTTP error redirection code
statistics.
