Florian Fainelli 02f1434d4e zd1211rw: wait between setting hash table and powering radio on
I am running Debian testing kernel 3.1.0-1-amd64, using a 079b:0062 Sagem
XG-76NA 802.11bg stick.

Upon zd1211rw interface
bringup (ifconfig wlan0 up) I get the following timeout:

[  950.330573] zd1211rw 1-3:1.0: phy2
[  955.108510] zd1211rw 1-3:1.0: firmware version 4725
[  955.148532] zd1211rw 1-3:1.0: zd1211b chip 079b:0062 v4810 high 00-19-70
AL2230_RF pa0 g--NS
[snip]
[  955.204072] zd1211rw 1-3:1.0: error ioread32(CR_REG1): -110

A second ifconfig wlan0 up brings the interface up without problems.

After a bit more debugging, the call trace is the following:

[10241.028130] zd1211rw 1-3:1.0: zd_chip_lock_phy_regs: error
ioread32(CR_REG1): -110
[10241.028140] zd1211rw 1-3:1.0: zd_switch_radio_on: failed to lock PHY regs
[10241.028148] zd1211rw 1-3:1.0: zd_op_start: failed to set radio on

Adding a 10 milliseconds delay between the call to set_mc_hash() and
zd_chip_switch_radio_on() allows successful interface bringups in all
cases and matches what the vendor driver did.
