As Hash based reo destination selection is configured,
the decapped packets reach different reo destintion rings
based on the destintaion ring selected for the computed hash (based on
the 5-tuple {ip src/ip dst/src port/dst port/protocol}) by hw and
as configured by driver.
Hence the current implementation of amsdu list based processing after all
the subframes of amsdu are received (since all msdu's for a pdev are
received in same reo dest ring), is not applicable here and hence is
replaced with per msdu based handling as these subframes
can be received in different reo dest rings.
Also, as some of the rx descriptor fields might be valid only for the
first msdu (for ex. received 80211 header, encryption type, etc),
it might not be useful now as we cannot sync between different
subframes received in different rings. Hence do not rely on those
fields and replace them with fieds valid only on per msdu descriptors.
Also cache other details such as encryption type for a peer so that
it can be reused when a packet is received from it.
