The VSC9953 Seville switch has 2 megabits of buffer split into 4360
words of 60 bytes each. 2048 * 1024 is 2 megabytes instead of 2 megabits.
2 megabits is (2048 / 8) * 1024 = 256 * 1024.

Maxim, networking maintainers apply patches on the master branch of one
of the 2 trees:
- https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git if
it's a new feature
- https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git if it's
a bug fix
Your patch applies to neither of these trees.
