Hi Dave.

This patch, commit b555cf4a50c17a9714715a2d7c8574dca1a7b356 ("mlxsw: spectrum:
Reduce number of supported 802.1D bridges") reduced the resources the
device allocates during init. Newer firmware versions now force a hard
limit on these resources and thus require this patch.

We would like to ask this commit be backported to stable kernels, so
that they can be used with newer firmware versions.

Thanks!

Jiri
