hi all,
I am try to define a hardware specific struct, it is like below:
struct xxx {
__be32 pdu_cnt:6;
__be32 y:3;
__be32 wep_key:2;
__be32 uses_wep_key:1;
__be32 keep_alive:1;
__be32 buff_tail_addr:19;
__be32 cts_11g:1;
__be32 rts_11g:1;
__be32 x:2;
__be32 frag_size:12;
__be32 payload_len:12;
__be32 frag_num:4;
}
but I am confuse with how to assign the values to the fields
"buff_tail_addr" and "payload_len", I think there are two ways to
assign values to them, but I don't know which is right?
eg: I declare a variable struct xxx X;
1: X.buff_tail_addr = 0x3456; X.payload_len = 0x20;
2: X.buff_tail_addr = cpu_to_be32(0x3456); X.payload_len = cpu_to_be16(0x20);
There are two way I think to assign values. Could anyone tell me which
is right or both are wrong? I will be appreciate for any hints, thanks
in advance!
