Subject: [PATCH 4.19 099/168] net: dsa: mv88e6xxx: MV88E6097 does not support jumbo configuration

From: Chris Packham <chris.packham@...iedtelesis.co.nz>

[ Upstream commit 0f3c66a3c7b4e8b9f654b3c998e9674376a51b0f ]

The MV88E6097 chip does not support configuring jumbo frames. Prior to
commit 5f4366660d65 only the 6352, 6351, 6165 and 6320 chips configured
jumbo mode. The refactor accidentally added the function for the 6097.
Remove the erroneous function pointer assignment.

Fixes: 5f4366660d65 ("net: dsa: mv88e6xxx: Refactor setting of jumbo frames")
