[PATCH v2 -next] drivers/net: netdevsim depends on INET

[Hongbo Yao]

If CONFIG_INET is not set and CONFIG_NETDEVSIM=y.
Building drivers/net/netdevsim/fib.o will get the following error:

drivers/net/netdevsim/fib.o: In function `nsim_fib4_rt_hw_flags_set':
fib.c:(.text+0x12b): undefined reference to `fib_alias_hw_flags_set'
drivers/net/netdevsim/fib.o: In function `nsim_fib4_rt_destroy':
fib.c:(.text+0xb11): undefined reference to `free_fib_info'

Correct the Kconfig for netdevsim.

Looks better :) Still missing a space between the hash and the bracket,
but:

While at it - does mlxsw have the same problem by any chance?

MLXSW_SPECTRUM depends on NET_SWITCHDEV which in turn depends on INET
