mlx5 PMDs use the mlx5_dev_to_pci_addr() routine to convert
Infiniband device name to the Bus-Device-Function location
on the PCI bus. The routine returned success even in case of
not found identification string. On caller side it likely
caused the wrong match with the BDF of previous device
resulting in wrong representor and master recognitions.

mlx5_nl_mac_addr_flush should flush all allocated MAC
addresses.
The MAC addresses array size should be of size
MLX5_MAX_MAC_ADDRESSES, but currently we return without
flushing the addresses if size is MLX5_MAX_MAC_ADDRESSES.
This was fixed by not allowing an array larger than
MLX5_MAX_MAC_ADDRESSES.

Several source files include Verbs header files as in (1). These source
files will not compile under non-Linux operating systems. This commit
removes this inclusion in two cases:
Case 1: There is no usage of ibv_* or mlx5dv_* symbols in the source
file so the inclusion in (1) can be safely removed.
Case 2: Verbs symbols are used. Please note the inclusion in (1) already
appears in file linux/mlx5_glue.h (which represents the interface

with (2). Under non-Linux operating systems - file mlx5_glue.h will not

This patch makes the Infiniband device physical port name
recognition more strict. Currently mlx5 PMD might recognize
the names like "pf0sf0" erroneously as "pf0" and the wrong
device type (host PF representor) is reported.
The names like "pf0sf0" belong to PCI subfunctions which
is currently not supported by mlx5 PMD and this false
recognition must be eliminated.

Some compilers raise an error when declaring a variable
in the middle of a function. This is a C99 allowance.
Even if DPDK switches globally to C99 or C11 standard,
the coding rules are for declarations at the beginning
of a block:
http://doc.dpdk.org/guides/contributing/coding_style.html#local-variables
This coding style is enforced by adding a check of
the common patterns like "for (int i;"
The occurrences of the checked pattern are fixed:
'for *(\(char\|u\?int\|unsigned\|s\?size_t\)'
In the file dpaa2_sparser.c, the fix is to remove the unused macros.

The mlx5_dev_to_pci_addr function defines a variable called ret inside a

During the loop, the function assigns a value within the variable and
breaks from the loop, so that this assigning has done nothing and is
actually unnecessary.

Flow tag action is supported only when the driver has DR or DV support.
The tag allocation is adjusted to the modes DV or DR.
In case both DR and DV are not supported in the system, the driver
handles static code for error report.
This error code, wrongly, was compiled when DV is supported while in
this case it cannot be accessed at all.
Ignore the aforementioned static error code in case of DV by
preprocessor commands rearrangement.

The new kernel adds the names like "pf0" for Host PCI physical
function representor on Bluefield SmartNIC hosts. This patch
provides correct HPF representor recognition over the kernel
versions 5.7 and laters.
The following port naming formats are supported:
- missing physical port name (no sysfs/netlink key) at all,
master is assumed
- decimal digits (for example "12"), representor is
assumed, the value is the index of attached VF
- "p" followed by decimal digits, for example "p2", master
is assumed
- "pf" followed by PF index, for example "pf0", Host PF
representor is assumed on SmartNIC systems.
- "pf" followed by PF index concatenated with "vf" followed by
VF index, for example "pf0vf1", representor is assumed.
If index of VF is "-1" it is a special case of Host PF
representor, this representor must be indexed in devargs
as 65535, for example representor=[0-3,65535] will
allow representors for VF0, VF1, VF2, VF3 and for host PF.
