[PATCH v2 2/2] recipes: add a delay when rx offload is turned off

[Jan Tluka]

This patch modifies all tests that set rx offload. We saw that setting
this offload off for certain NICs such as ixgbe does reset of the device.
Therefore the link goes down and a delay has to be added after the
offload setting so that data sent over the device pass through.
