Hi all,

Please tell me the difference between using unsigned short and __be16
to declear a variable in a data structure.
For example, in include/net/inet_sock.h, struct inet_sock is decleared as

struct inet_sock {
??????? __be16????????????????? inet_dport;
};

not

struct inet_sock {
????????unsigned short????????????????? inet_dport;
};

This is mostly to avoid confusion about where byte order conversation has to
be done. When reading "unsigned short" you would normally expect the variable
to contain host byte order.
