From: Arnd Bergmann <arnd@arndb.de>
The newly added offload code fails to link when IPv4 networking is disabled:
arm-linux-gnueabi-ld: drivers/net/ethernet/intel/idpf/idpf_txrx.o: in function `idpf_vport_splitq_napi_poll':
idpf_txrx.c:(.text+0x7a20): undefined reference to `tcp_gro_complete'
Add complile-time checks for both CONFIG_INET (ipv4) and CONFIG_IPV6
in order to drop the corresponding code when the features are unavailable.
This should also help produce slightly better output for IPv4-only
kernel builds, if anyone still uses those.
Fixes: 3a8845af66edb ("idpf: add RX splitq napi poll support")
