Subject: sfc: Fix MCDI command size for filter operations
From: Martin Habets <mhabets@xxxxxxxxxxxxxx>
[ Upstream commit bb53f4d4f5116d3dae76bb12fb16bc73771f958a ]
The 8000 series adapters uses catch-all filters for encapsulated traffic
to support filtering VXLAN, NVGRE and GENEVE traffic.
This new filter functionality requires a longer MCDI command.
This patch increases the size of buffers on stack that were missed, which
fixes a kernel panic from the stack protector.
Fixes: 9b41080125176 ("sfc: insert catch-all filters for encapsulated traffic")
