Subject: [PATCH 2/2] kni: fix build for igb_ndo_bridge_setlink in Linux 5.0
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Build error seen with Linux kernel 5.0 and
when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled.
build error:
.../build/build/kernel/linux/kni/igb_main.c:2348:24:
error: initialization of
‘int (*)(struct net_device *, struct nlmsghdr *, u16,
struct netlink_ext_ack *)’
{aka ‘int (*)(struct net_device *, struct nlmsghdr *,
short unsigned int, struct netlink_ext_ack *)’}
from incompatible pointer type
‘int (*)(struct net_device *, struct nlmsghdr *, u16)’
{aka ‘int (*)(struct net_device *, struct nlmsghdr *,
short unsigned int)’}
[-Werror=incompatible-pointer-types]
.ndo_bridge_setlink = igb_ndo_bridge_setlink,
^~~~~~~~~~~~~~~~~~~~~~
.../build/build/kernel/linux/kni/igb_main.c:2348:24:
note: (near initialization for ‘igb_netdev_ops.ndo_bridge_setlink’)
igb_ndo_bridge_setlink() is changed in Linux kernel version 5.0
and now requires a new parameter, 'struct netlink_ext_ack *extack'.
Fixed by adding a new parameter with a kernel version check.
