This commit applies "net_shared.h" to BPF programs to remove existing network related header dependencies. Also, this commit removes unnecessary headers before applying "vmlinux.h" to the BPF programs. Mostly, endianness conversion function has been applied to the source. In addition, several macros have been defined to fulfill the INET, TC-related constants. Signed-off-by: Daniel T.
