macsec: restore uAPI after addition of GCM-AES-256
Commit ccfdec908922 ("macsec: Add support for GCM-AES-256 cipher suite")
changed a few values in the uapi headers for MACsec.
Because of existing userspace implementations, we need to preserve the
value of MACSEC_DEFAULT_CIPHER_ID. Not doing that resulted in
wpa_supplicant segfaults when a secure channel was created using the
default cipher. Thus, swap MACSEC_DEFAULT_CIPHER_{ID,ALT} back to their
original values.
Changing the maximum length of the MACSEC_SA_ATTR_KEY attribute is
unnecessary, as the previous value (MACSEC_MAX_KEY_LEN, which was 128B)
is large enough to carry 32-bytes keys. This patch reverts
MACSEC_MAX_KEY_LEN to 128B and restores the old length check on
MACSEC_SA_ATTR_KEY.
