From: Arnd Bergmann <arnd@xxxxxxxx>
The new irdma_iw_get_vlan_prio() function requires IPv6 support to build:
x86_64-linux-ld: drivers/infiniband/hw/irdma/cm.o: in function `irdma_iw_get_vlan_prio':
cm.c:(.text+0x2832): undefined reference to `ipv6_chk_addr'
Add a compile-time check in the same way as elsewhere in this file to avoid
this by conditionally leaving out the ipv6 specific bits.
Fixes: f877f22ac1e9b ("RDMA/irdma: Implement egress VLAN priority")
