My understanding is p has to be initialized: the only way out of the
while(1) loop below sets it.

There is no additional safety here.
The for loop ensures that i is positive as num_ioq_vector is also
int and so i can not be negative as it's incremented from 0.

There is a regular need in the kernel to provide a way to declare

Kernel code should always use "flexible array members"[1] for these

The function sockfd_lookup uses fget on the value that is stored in

applied to this value. This can be done directly, but it seems better
to use the specific macro sockfd_put, which does the same thing.

This is all in userspace, in the ethtool code.
What about the global offset that w

Before commit 889b8f964f2f ("packet: Kill CONFIG_PACKET_MMAP.") there
used to be a CONFIG_PACKET_MMAP config symbol that depended on
CONFIG_PACKET. The text still implies that PACKET_MMAP can be disabled.
Remove that from the text, as well as reference to old kernel versions.

This patch is used to construct skb based on page to save memory copy
overhead.
Taking into account the problem of addr unaligned, and the
possibility of frame size greater than page in the future.
The test environment is Aliyun ECS server.
Test cmd:
```
xdpsock -i eth0 -t -S -s
