net/enic: fix Rx queue init after restarting a device

If you stop, then start a port that had already received some packets,
the NIC could fetch discriptors from the wrong location. This could
effectivly reduce the size of the Rx queue by a random amount and
cause packet drop or reduced performance.

Reset the NIC fetch index to 0 when allocating and posting mbuf
addresses to the NIC.

net/fm10k: fix Rx descriptor read timing

We find that when traffic is light, a small number of packets will have
wrong metadata (e.g. packet type), however this issue will not happen
when traffic is heavy.

The root cause is some fields in fm10k_rx_desc are read at the wrong time,
since the descriptor (being 16-bytes big) is not read as a single atomic
operation. When the input speed is slower than software's capability,
fm10k scalar Rx function accesses descriptors at about the same time
as HW writes them, so the scenario can occur: some fields like pkt_info
in fm10k_rx_desc are read before HW writeback but some fields like DD bit
are read after HW writeback, this will lead to the later packet parsing
function using incorrect value.

This patch fixes this issue by reading and parsing Rx descriptor only after

8 years agocrypto/kasumi: fix AAD size of F9 function

crypto/kasumi: fix AAD size of F9 function

Additional authenticated data (AAD) in KASUMI F9 (UIA1) is 8 bytes
and not 9 bytes, since direction bit is obtained just after the
end of the message, and it is separated from the AAD.
