net: enetc: check whether the RSS algorithm is Toeplitz
Both ENETC v1 and v4 only provide Toeplitz RSS support. This patch adds
a validation check to reject attempts to configure other RSS algorithms,
avoiding misleading configuration options for users.
Fixes: d382563f541b ("enetc: Add RFS and RSS support")
