> Updated the comment preceding the 'rearm_data' fields to reflect that some

> rearm, but rather when pulling the packet from the descriptor.
> By doing this, they avoid a store operation into the mbuf when they rearm
> the Rx descriptor, and instead postpone it to later, where it will be
> combined with other store operations into the mbuf.
> 
> Updated the comment describing what the second cache line is used for, to
> reflect that there are exceptions, where some fields are set on Rx too.
> 
> Updated comments describing what needs to be updated when adding new Rx
