This series fixes two correctness issues in the cxgbe PMD that can cause
traffic loss on Chelsio T6 adapters, especially when rte_flow QUEUE
rules concentrate ingress on a small set of RX queues. 

Patch 1 fixes packed Rx response handling. The current PMD assumes every
response descriptor starts a new Free List buffer by requiring
F_RSPD_NEWBUF on each response. That assumption does not always hold for
packed ingress responses. Under sustained small-packet traffic to a
single ingress queue, the FL/IQ state goes out of sync and the affected
Rx path stops making forward progress. 

Patch 2 scopes rte_flow rules to the ingress port they were created on.
Chelsio filters are programmed in adapter-wide tables, and the PMD
already supports the iport field in the hardware filter spec. However,
the flow parser never fills it for normal per-port rules, so a rule
created on one port can also match traffic arriving on sibling ports of
the same adapter. 

Both issues reproduce with stock testpmd on T62100-LP-CR. The per-patch
commit messages include the details and reproducers.
