[PATCH 5.10 13/57] net: ipv4: Publish fib_nlmsg_size()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Amit Cohen <amcohen@nvidia.com>

[ Upstream commit 1e7bdec6bbc7816cdc6a093374f4bf4e732c3d44 ]

Publish fib_nlmsg_size() to allow it to be used later on from
fib_alias_hw_flags_set().

Remove the inline keyword since it shouldn't be used inside C files.
