Subject: [PATCH net-next 01/10] net/mlx5e: Factor out IPsec ASO update function

From: Leon Romanovsky <leonro@...dia.com>

The ASO update is common operation which is going to be used in next
patch, so as a preparation, let's refactor the code for future reuse.

As part of this refactoring, not used function argument was removed too.
