[SCSI] fcoe: make it possible to verify fcoe with sparse
Analyzing fcoe with sparse currently fails. This is because struct
fcoe_rcv_info contains two enum members that have been declared with
__attribute__((packed)). Apparently gcc honors this attribute while sparse
ignores it. The result is that sizeof(struct fcoe_rcv_info)
== sizeof(struct sk_buff::cb) == 48 on a 64-bit system according to gcc, but
not according to sparse. The patch below modifies the definition of
struct fcoe_rcv_info such that gcc and sparse interpret this structure
definition in the same way. The current sparse output is as follows:
$ cd linux-2.6.34
$ make C=2 M=drivers/scsi/fcoe modules
CHECK drivers/scsi/fcoe/fcoe.c
include/scsi/fc_frame.h:81:9: error: invalid bitfield width, -1.
