I don't see that we're in an atomic context so there's no need to

See also Documentation/timers/timers-howto.txt. It states:
"In general, use of mdelay is discouraged and code should
be refactored to allow for the use of msleep."

The change is the same as ("kernel/generic: modify mtd related

directory of specific kernel version, better to also change them. So
it will avoid adding files to future specific files directory

Gabor Juhos 30ebad2dee ar71xx: ag71xx: increase calculated max frame length value
The r39147 commit introduces a regression: at lease on some routers
with ar8216 switch large packets get lost if 802.1q tagged port is
used on the interface connected to the aforementioned switch.

The r39147 changes code in the way so interface is set to accept
packets no longer than max ethernet frame length for a given mtu.

Unfortunately ar8216 has a feature: it sends two additional bytes
as a packet header and those this header needs to be added to the
max frame length. Otherwise long enough packets get lost.

The problem only manuifests itself if interface is used in vlan
tagged mode. If interface is untagged then ar8216's header fits
into space used by 802.1q tag and not packets are lost.

Include two additional bytes in the max frame length calculation
to fix the issue.

This patch is tested and works with Trendnet TEW-632BRP.

Gabor Juhos 2b220f3550 ar71xx: ag71xx: fix max frame length setup of the built-in switches
The currently used bitmask of the maximum frame length field
is wrong for both models. On AR724x/AR933x the largest frame
size is 2047 bytes, on the AR934x it is 16383 bytes.

Make the MTU setup code model specific, and use the correct
bitmask for both models. Also change the value to the maximum.

Gabor Juhos 31de995025 ar71xx: ag71xx: compute the RX buffer size from the maximum frame size
Currently, the AG71XX_RX_PKT_SIZE value limits the received
frame size to 1514/1516 bytes with/without a VLAN header
respectively. However the hardware limit is controlled by
the value the AG71XX_REG_MAC_MFL register which contains
the value of the max_frame_len field.

Compute the RX buffer size from the max_frame_len field
to get rid of the 1514/1516 byte limitation. Also remove
the unused AG71XX_RX_PKT_SIZE definition.

Gabor Juhos 0d7a6748e1 ag71xx: ag71xx: use device name for debugfs entry
The ag71xx debugfs code uses the network device name
for the device specific debugfs directory. Since r38689
'ar71xx: ag71xx: fix a race involving netdev registration'
the debugfs initialization happens before the ethernet
device gets registered and the network device name contains
'eth%d' at this point. If the board setup code registers
multiple ag71xx devices, the debugfs code tries to create
the device specific dir with the same name which causes
an error like this:

  eth0: Atheros AG71xx at 0xba000000, irq 5, mode:GMII
  ag71xx ag71xx.0: connected to PHY at ag71xx-mdio.1:04 [uid=004dd041, driver=Generic PHY]
  ag71xx: probe of ag71xx.0 failed with error -12

Use the device name for the debugfs directory to avoid the
collisions. Also add an error message and change the return
code if the debugfs_create_dir call fails.

Gabor Juhos 7bd3a7bc7b ar71xx: ag71xx: fix a race involving netdev registration
In particular, phy_connect before register_netdev. This is because
register_netdev runs the netdev notifiers, which can race with the rest of
the initialization in ag71xx_probe. In my case this manifested in two ways:

1) If ag71xx is compiled as a module and inserted after netifd has started,
   netifd is notified by register_netdev before the call to
   ag71xx_phy_connect. netifd tries to bring the interface up, which calls
   ag71xx_open, which in turn enters ag71xx_phy_start. This keys off
   ag->phy_dev (which is still NULL) and thinks this is a fixed-link board,
   and enters ag71xx_link_adjust. This looks at ag->speed which is not yet
   initialized and hits the BUG() in the switch (ag->speed) in
   ag71xx_link_adjust.

   This is the wrong code path for ag71xx_phy_start - my board has PHYs that
   need to be brought up with phy_start. Doing ag71xx_phy_connect before
   register_netdev ensures that ag->phy_dev is non-NULL before
   ag71xx_phy_start is ever called.

2) When ag71xx is built into the kernel, and netconsole is enabled, there
   is a gap in the initial burst of replayed printks right after the netdev
   comes up. My assumption is that netconsole is also triggered by a netdev
   notifier, and part of this printk burst happens before the call into
   ag71xx_phy_connect, so part of the burst is lost while the PHY comes up.
   This patch fixes the gap - all the printks before eth0 comes up are bursted
   in full when netconsole initializes.

ag71xx_phy_connect_xxx no longer runs with a registered netdev, so the
logging has been adjusted accordingly to avoid "unregistered net_device" or
"eth%d" messages in dmesg.
