Only two of the boards supported by this driver have an 8254 counter/timer.
Both of these boards have a single 8254 device. Currently the counter
subdevice functions are coded to support multiple 8254 devices. This is
unnecessary and just complicates the code.
Simplfy the subdevice functions to work for a single 8254 counter/timer and
refactor the driver (*attach) accordingly.

staging: comedi: comedi_8254: introduce module for 8254 timer support
A 8254 timer/counter is commonly used on data acquisition boards to provide
the internal pacer clock used to acquire analog input samples. Some boards
also to allow the timers to be used externally.
Currently the 8254 timers are supported by comedi using the 8253.h header
and a number of inline functions. This works for the internal pacer clock
but requires the drivers to implement subdevice code necessary to use the
timers externally.
Introduce a new module to support both the internal pacer clock and the
external counter subdevice. This will allow removing a bunch of duplicated
code in the drivers and standardizes the comedi 8254 timer support.
This implementation is based on the 8253.h inline functions and the various
subdevice functionality in the comedi drivers.

This patch replaces memcpy with ether_addr_copy.

__u16 cmd; /* 2 2 */
/* XXX 4 bytes hole, try to pack */

/* typedef sa_family_t -> __kernel_sa_family_t */ short unsigned int sa_family; /* 8 2 */
char sa_data[14]; /* 10 14 */
} ap_addr; /* 16 */
sa_data is a char array of size 14, and the number of bytes copied using
ether_addr_copy() is 6.
Second argument is network->bssid and output of pahole is:
struct rtllib_network {
