net: ipv6: fix kconfig dependency warning for IPV6_SEG6_HMAC
When IPV6_SEG6_HMAC is enabled and CRYPTO is disabled, it results in the
following Kbuild warning:
WARNING: unmet direct dependencies detected for CRYPTO_HMAC
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- IPV6_SEG6_HMAC [=y] && NET [=y] && INET [=y] && IPV6 [=y]
WARNING: unmet direct dependencies detected for CRYPTO_SHA1
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- IPV6_SEG6_HMAC [=y] && NET [=y] && INET [=y] && IPV6 [=y]
WARNING: unmet direct dependencies detected for CRYPTO_SHA256
Depends on [n]: CRYPTO [=n]
Selected by [y]:
- IPV6_SEG6_HMAC [=y] && NET [=y] && INET [=y] && IPV6 [=y]
The reason is that IPV6_SEG6_HMAC selects CRYPTO_HMAC, CRYPTO_SHA1, and
CRYPTO_SHA256 without depending on or selecting CRYPTO while those configs
are subordinate to CRYPTO.
Honor the kconfig menu hierarchy to remove kconfig dependency warnings.
