drivers/net: support single queue per port

When configuring DPDK for one queue per port
(#define RTE_MAX_QUEUES_PER_PORT 1), compilation of some network drivers
fails with e.g.:

../drivers/net/bnxt/bnxt_rxq.c: In function 'bnxt_rx_queue_stop':
../drivers/net/bnxt/bnxt_rxq.c:587:34: error: array subscript 1 is above array bounds of 'uint8_t[1]' {aka 'unsigned char[1]'} [-Werror=array-bounds=]
587 | dev->data->rx_queue_state[q_id] = RTE_ETH_QUEUE_STATE_STOPPED;
| ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~
In file included from ../drivers/net/bnxt/bnxt.h:16,
from ../drivers/net/bnxt/bnxt_rxq.c:10:
../lib/ethdev/ethdev_driver.h:168:17: note: while referencing 'rx_queue_state'
168 | uint8_t rx_queue_state[RTE_MAX_QUEUES_PER_PORT];
| ^~~~~~~~~~~~~~

To fix this, a hint is added to the network drivers where a compiler in
the CI has been seen to emit the above error when DPDK is configured for
one queue per port, but we know that the error cannot occur.

Missing "RTE_PTYPE_UNKNOWN" ptype causes buffer overflow.
Enhance code such that the dev_supported_ptypes_get()

User can still use `RTE_ETH_RX_OFFLOAD_BUFFER_SPLIT` for per-queue packet
split offload, which is configured by 'rte_eth_rxseg_split'.

drivers/net: advertise no support for keeping flow rules

When RTE_ETH_DEV_CAPA_FLOW_RULE_KEEP capability bit is zero,
the specified behavior is the same as it had been before
this bit was introduced. Explicitly reset it in all PMDs
supporting rte_flow API in order to attract the attention
of maintainers, who should eventually choose to advertise
the new capability or not. It is already known that
mlx4 and mlx5 will not support this capability.

For RTE_ETH_DEV_CAPA_FLOW_SHARED_OBJECT_KEEP
similar action is not performed,
because no PMD except mlx5 supports indirect actions.
Any PMD that starts doing so will anyway have to consider
all relevant API, including this capability.

Removing 'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag.

Instead of drivers announce this capability, application can deduct the
capability by checking reported 'dev_info.max_mtu' or

And instead of application setting this flag explicitly to enable jumbo

'RTE_ETHER_MTU'.

Removing this additional configuration for simplification.
