-
-We need to ensure there is enough headroom to push extra header,
-but we also need to check if we are allowed to change headers.
-
-skb_cow_head() is the proper helper to deal with this.

-Subject: netfilter: nf_tables: fix mismatch in big-endian system
-
-Currently, there are two different methods to store an u16 integer to
-the u32 data register. For example:
- u32 *dest = &regs->data[priv->dreg];
- 1. *dest = 0; *(u16 *) dest = val_u16;
- 2. *dest = val_u16;
-
-For method 1, the u16 value will be stored like this, either in
-big-endian or little-endian system:
- 0 15 31
- +-+-+-+-+-+-+-+-+-+-+-+-+
- | Value | 0 |
- +-+-+-+-+-+-+-+-+-+-+-+-+
-
-For method 2, in little-endian system, the u16 value will be the same
-as listed above. But in big-endian system, the u16 value will be stored
-like this:
- 0 15 31
- +-+-+-+-+-+-+-+-+-+-+-+-+
- | 0 | Value |
- +-+-+-+-+-+-+-+-+-+-+-+-+
-
-So later we use "memcmp(&regs->data[priv->sreg], data, 2);" to do
-compare in nft_cmp, nft_lookup expr ..., method 2 will get the wrong
-result in big-endian system, as 0~15 bits will always be zero.
-
-For the similar reason, when loading an u16 value from the u32 data
-register, we should use "*(u16 *) sreg;" instead of "(u16)*sreg;",
-the 2nd method will get the wrong value in the big-endian system.
-
-So introduce some wrapper functions to store/load an u8 or u16
-integer to/from the u32 data register, and use them in the right
-place.

-Subject: uapi/if_ether.h: prevent redefinition of struct ethhdr
-
-Musl provides its own ethhdr struct definition. Add a guard to prevent
-its definition of the appropriate musl header has already been included.
-
-glibc does not implement this header, but when glibc will implement this
-they can just define __UAPI_DEF_ETHHDR 0 to make it work with the
-kernel.
