In E-Switch steering domain there was dedicated default miss action
created for every sampling flow.
The patch replaces this one with the global default miss action.

Hi Jiawei,

The impact of the patch is not clear, what was the problem using action per 
flow? What will change when global action is used? Is this fixing some problem 
or is it optimization by preventing per flow action?

Since this looks like optimization, I am removing the stable tag for now.

If it is a fix, please reply with a fixes line, I can update it in next-net.

Yes please we must avoid "Cc: stable" without a "Fixes:" line.

The patch is optimization not fix,  MLX5 PMD can reuses the global action don’t need allocate new one each time.

Yes,  please remove this tag.
