[ Upstream commit 8f4cd89bf10607de08231d6d91a73dd63336808e ]
Set eswitch inline-mode to be u8, not u16. Otherwise, errors below
$ devlink dev eswitch set pci/0000:08:00.0 mode switchdev \
inline-mode network
Error: Attribute failed policy validation.
kernel answers: Numerical result out of rang
netlink: 'devlink': attribute type 26 has an invalid length.
Fixes: f2f9dd164db0 ("netlink: specs: devlink: add the remaining command to generate complete split_ops")
