Subject: [PATCH net-next] net: blackhole_dev: fix build warning for ethh set but not used
Date: Fri,  2 Feb 2024 07:13:29 -0800

lib/test_blackhole_dev.c sets a variable that is never read, causing
this following building warning:

	lib/test_blackhole_dev.c:32:17: warning: variable 'ethh' set but not used [-Wunused-but-set-variable]

Remove the variable struct ethhdr *ethh, which is unused.
