[PATCH 6/7] net/memif: fix const pointer in socket check

[David Marchand]

With latest glibc (Fedora Rawhide):
../drivers/net/memif/rte_eth_memif.c: In function
	'memif_check_socket_filename':
../drivers/net/memif/rte_eth_memif.c:1848:13: warning: assignment discards
	'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
 1848 |         tmp = strrchr(filename, '/');
      |             ^

Fixes: 09c7e63a71f9 ("net/memif: introduce memory interface PMD")
