octeontx2-af: Verify NPA/SSO/NIX PF_FUNC mapping
While mapping a NIX LF to a NPA LF attached PF_FUNC or SSO LF attached PF_FUNC, verify if PF_FUNC is valid and if that PF_FUNC has a LF of that block attached to it or not. Signed-off-by: Sunil Goutham <sgoutham@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
