Consider the following situation:
 * a dump that would show 8 entries, four in the first
   round, and four in the second
 * between the first and second rounds, 6 entries are
   removed
 * now the second round will not show any entry, and
   even if there is a sequence/generation counter the
   application will not know

To solve this problem, add a new flag NLM_F_DUMP_INTR
to the netlink header that indicates the dump wasn't
consistent, this flag can also be set on the MSG_DONE
message that terminates the dump, and as such above
situation can be detected.

To achieve this, add a sequence counter to the netlink
callback struct. Of course, netlink code still needs
to use this new functionality. The correct way to do
that is to always set cb->seq when a dumpit callback
is invoked and call nl_dump_check_consistent() for
each new message. The core code will also call this
function for the final MSG_DONE message.

To make it usable with generic netlink, a new function
genlmsg_nlhdr() is needed to obtain the netlink header
from the genetlink user header.

After uploading radio values calibration goes in. In MMIO dump it is:
 radio_read(0x002b) -> 0x0008
radio_write(0x002b) <- 0x0008
 radio_read(0x002e) -> 0x0004
radio_write(0x002e) <- 0x0000
 radio_read(0x002e) -> 0x0000
radio_write(0x002e) <- 0x0004
 radio_read(0x002b) -> 0x0008
radio_write(0x002b) <- 0x0009
To find masks and sets, MMIO hacks were used to fool closed driver.

Whereas replugging device make it functional. To solve that problem
force reset device during probe.

With patch messages are gone. Unfortunately device may sometimes
still does not operate correctly after module reload (fail to receive
data after associate), but such cases are rarer than without the patch.

Closed drivers kill radio right after reading radio version and MACCTL,
so it was easy to find related PHY ops:
 phy_read(0x0810) -> 0x0000
phy_write(0x0810) <- 0x0000
To find out the mask of above OP, MMIO hack was used to fake read val:

        Susinder suggests that the ideal power range value should be

common check for all platforms we take agc2_power should be atleast greater
