80bfab79b8 net: adopt skb_network_offset() and similar helpers
This is a cleanup patch, making code a bit more concise.

1) Use skb_network_offset(skb) in place of
       (skb_network_header(skb) - skb->data)

2) Use -skb_network_offset(skb) in place of
       (skb->data - skb_network_header(skb))

3) Use skb_transport_offset(skb) in place of
       (skb_transport_header(skb) - skb->data)

4) Use skb_inner_transport_offset(skb) in place of
       (skb_inner_transport_header(skb) - skb->data)

aefd013624 net: txgbe: use irq_domain for interrupt controller
In the current interrupt controller, the MAC interrupt acts as the
parent interrupt in the GPIO IRQ chip. But when the number of Rx/Tx
ring changes, the PCI IRQ vector needs to be reallocated. Then this
interrupt controller would be corrupted. So use irq_domain structure
to avoid the above problem.

738b54b9b6 net: libwx: fix memory leak on free page
ifconfig ethx up, will set page->refcount larger than 1,
and then ifconfig ethx down, calling __page_frag_cache_drain()
to free pages, it is not compatible with page pool.
So deleting codes which changing page->refcount.

a9ca9f9cef page_pool: split types and declarations from page_pool.h
Split types and pure function declarations from page_pool.h
and add them in page_page/types.h, so that C sources can
include page_pool.h and headers should generally only include
page_pool/types.h as suggested by jakub.
Rename page_pool.h to page_pool/helpers.h to have both in
one place.
