net: netpoll: Individualize the skb pool
[ Upstream commit 221a9c1df790fa711d65daf5ba05d0addc279153 ]
The current implementation of the netpoll system uses a global skb
pool, which can lead to inefficient memory usage and
waste when targets are disabled or no longer in use.
This can result in a significant amount of memory being unnecessarily
allocated and retained, potentially causing performance issues and
limiting the availability of resources for other system components.
Modify the netpoll system to assign a skb pool to each target instead of
using a global one.
This approach allows for more fine-grained control over memory
allocation and deallocation, ensuring that resources are only allocated
and retained as needed.
