Retrieving network interface index via Netlink fails in

routine fails due to RDMA_NLDEV_ATTR_NDEV_INDEX attribute is not
supported by the old driver.
The patch allowing to retrieve the network interface index and
name via Netlink [1]. So, the problem depends on ib_core module
version - 4.16 supports getting ifindex via Netlink, 4.15 does not.
This error was ignored in previous versions of MLX5 PMD probing
routine. For single device ifindex was retrieved via sysfs
and link control was not lost, so problem just was not noticed.
In order to support MLX5 PMD functioning over old kernel driver
this patch adds ifindex retrieving via sysfs into probing routine.
It is worth to note this method works for master/standalone
device only.

Do a global replace of snprintf(..."%s",...) with strlcpy, adding in the
rte_string_fns.h header if needed. The function changes in this patch were
auto-generated via command:
spatch --sp-file devtools/cocci/strlcpy.cocci --dir . --in-place
and then the files edited using awk to add in the missing header:
gawk -i inplace '/include <rte_/ && ! seen { \
print "#include <rte_string_fns.h>"; seen=1} {print}'

replace snprintf with strlcpy without adding extra include
For files that already have rte_string_fns.h included in them, we can
do a straight replacement of snprintf(..."%s",...) with strlcpy. The
changes in this patch were auto-generated via command:
spatch --sp-file devtools/cocci/strlcpy-with-header.cocci --dir . --in-place

devtools/cocci: create safer version of strlcpy script
The existing cocci script for coccinelle replaces all matching instances
of snprintf() with strlcpy() without regards to header inclusion. To allow
changes without build errors, we create a safer version of this script
that only makes changes when the rte_string_fns.h header is already
included.
