net/ena: validate Rx req ID upon acquiring descriptor
Instead of verifying the Rx descriptor each time it's being used in the
driver code, now the verification happens on the HAL side.
This simplifies code a lot as instead of doing 2 validations, only
single one is needed. The driver have to check the rc value returned
by the ena_com upon reading the Rx descriptor and trigger the reset
if needed. It was previously the responsibility of the
validate_rx_req_id() function.
As part of the change, the version of the driver was bumped to v2.2.1.

When testing high performance numbers, it is often that CPU performance

app/testpmd: fix setting maximum packet length
"port config all max-pkt-len" command fails because it doesn't set the

Commit in the fixes line moved the 'DEV_RX_OFFLOAD_JUMBO_FRAME' offload
flag update from 'cmd_config_max_pkt_len_parsed()' to 'init_config()'.
'init_config()' function is only called during testpmd startup, but the
flag status needs to be calculated whenever 'max_rx_pkt_len' changes.
The issue can be reproduced as [1], where the 'max-pkt-len' reduced and
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag should be cleared but it
didn't.
Adding the 'update_jumbo_frame_offload()' helper function to update
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag and 'max_rx_pkt_len'. This
function is called both by 'init_config()' and
'cmd_config_max_pkt_len_parsed()'.
Default 'max-pkt-len' value set to zero, 'update_jumbo_frame_offload()'
updates it to "RTE_ETHER_MTU + PMD specific Ethernet overhead" when it
is zero.
If '--max-pkt-len=N' argument provided, it will be used instead.
And with each "port config all max-pkt-len" command, the
'DEV_RX_OFFLOAD_JUMBO_FRAME' offload flag, 'max-pkt-len' and MTU is
updated.

net/nfp: create separate entity for PF device
Before this change memory for the private data of all physical ports
where allocated with single rte_zmalloc() call. Specific port private
data was accessed by means of an offset into this memory. This scheme is
problematic when attempting to free only one port's private data at a
time.
To address this, a new entity is created called struct nfp_pf_dev. This
struct represents the PF device. It has a number of PF specific members.
Notably it has a pointer of type rte_eth_dev that points to the eth_dev
associated with the first physical port of the device. It also has an
array of nfp_net_hw's containing pointers to all the physical ports
under the PF.
Memory is first allocated for the PF and PF specific initialization is
attempted. Next, all the physical ports under the PF is iterated and
memory is allocated separately for the private data of each port. Port 0
is skipped during this phase because memory has already been allocated
and an eth_dev already exits for the 0th port.
