[bluetooth-dev] ask about the hci.c



Dear,

In the hci.c, there is a function: set_acl_hdr(...).
set_acl_hdr(u8 *data, u32 len, u8 pb, u8 bc, u32 hci_hdl)
{
	u32 tmp_hdr = 0;

	SET_BITS(tmp_hdr, 0, 12, hci_hdl);
	SET_BITS(tmp_hdr, 12, 2, pb);
	SET_BITS(tmp_hdr, 14, 2, bc);
	SET_BITS(tmp_hdr, 16, 16, len);

	data[0] = ACL_PKT;
	put_unaligned(cpu_to_le32(tmp_hdr), (u32*)&data[1]);
}
I think the SET_BITS(tmp_hdr, 16, 16, len) should be SET_BITS(tmp_hdr,
16, 31, len),because the total len of HCI DATA PACKET is 32 bits. It is
right,ok?
