Message

Hi all,

I am resending that two changes again.

This are two patches to cdc_ncm driver used in our DisplayLink USB docking stations.
They are independent, however both of them are improving performance and stability so it matches Windows experience.

It is improving the experience for users of millions of DisplayLink-based docking stations that are in the wild.
That tweaks of NTB TX/RX results in approximately 4-5x available bandwidth improvement in extreme cases.


Please take a look.
