501505c560 net/mlx: fix IPv4 and IPv6 packet type
Mellanox PMDs do not differentiate IP header with or without options, so
the advertised packet type for an IPv4 should not be RTE_PTYPE_L3_IPV4,
which explicitly means "does not contain any header option".

Change the driver to set
RTE_PTYPE(_INNER)_L3_IPV4_EXT_UNKNOWN or
RTE_PTYPE(_INNER)_L3_IPV6_EXT_UNKNOWN flags for all IPv4/IPv6 packets
received.

Fixes: 429df3803a ("mlx4: replace some offload flags with packet type")
Fixes: 67fa62bc67 ("mlx5: support checksum offload")

2c960a5116 net/mlx: remove link update lock
Retrieving link status information through the link update callback should
be quick and non-blocking.

Mellanox PMDs retrieve this information through ioctl() calls on the
related kernel netdevice. This appears to take a long time to
complete and may cause significant slowdowns in applications.

While these system calls cannot be accelerated, removing the lock on the
private structure allows applications to perform other control operations
from separate threads in the meantime. This function remains safe without
locking as it does not write the private structure, it is only used to
retrieve the name of the netdevice.

30807f62b2 net/mlx5: fix Tx doorbell
Too much data is uselessly written to the Tx doorbell, which since v16.11
may also cause Tx queues to behave erratically and crash applications.

This regression was seen on VF devices when the BlueFlame buffer size is
zero (txq->bf_buf_size) due to the following change:

 -       txq->bf_offset ^= txq->bf_buf_size;
 +       txq->bf_offset ^= (1 << txq->bf_buf_size);
