[dpdk-stable] [PATCH 17.11 2/2] net/nfp: replace strncpy by strlcpy

[Yongseok Koh <yskoh@mellanox.com>]

GCC 8.1 error:

drivers/net/nfp/nfp_nspu.c: In function
‘nfp_nspu_set_bar_from_symbl.constprop’:
drivers/net/nfp/nfp_nspu.c:426:2: error: ‘strncpy’ output truncated
before terminating nul copying as many bytes from a string as its length
[-Werror=stringop-truncation]
  strncpy(sym_buf, symbl, strlen(symbl));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
