[PATCH v2 00/10] Part 4: handle addr_assign_type for random addresses

[PATCH v2 00/10] Part 4: handle addr_assign_type for random addresses

[Danny Kukawka]

The fourth part of my patch series to fix the handling of 
addr_assign_type for random MAC addresses. 

This most of the patches in this series are for slightly 
more complex cases to handle addr_assign_type and the
reset to NET_ADDR_PERM as soon as the MAC get changed via 
.ndo_set_mac_address where eth_mac_addr wasn't used.

Danny Kukawka (10):
  au1000_eth: use eth_hw_addr_random() instead of random_ether_addr()
  lantiq_etop: set addr_assign_type if random_ether_addr() used
  davinci_emac: use eth_hw_addr_random() instead of random_ether_addr()
  xilinx ll_temac: use eth_hw_addr_random() instead of
    random_ether_addr()
  igbvf: reset netdevice addr_assign_type if changed
  batman-adv: use eth_hw_addr_random() instead of random_ether_addr()
  cisco/enic: use eth_hw_addr_random() instead of random_ether_addr()
  ethoc: set addr_assign_type if random_ether_addr() used
  atheros eth: set addr_assign_type if random_ether_addr() used
  UML net: set addr_assign_type if random_ether_addr() used

[PATCH v2 01/10] au1000_eth: use eth_hw_addr_random() instead of random_ether_addr()

Use eth_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

[PATCH v2 07/10] cisco/enic: use eth_hw_addr_random() instead of random_ether_addr()

[Danny Kukawka]

Use dev_hw_addr_random() instead of calling random_ether_addr()
to set addr_assign_type correctly to NET_ADDR_RANDOM.

Couldn't replace random_ether_addr() in enic_probe() since
enic_set_mac_addr() is used which would reset addr_assign_type.
Instead set addr_assign_type directly to NET_ADDR_RANDOM in
case of random mac after call enic_set_mac_addr().

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

Set addr_assign_type correctly to NET_ADDR_RANDOM in case
a random MAC address was generated and assigned to the netdevice.

Fixed ethoc_set_mac_address() to check if the given mac
address is valid and set also dev_addr of the net_device.
Check also the return value of ethoc_set_mac_address() in
ethoc_probe().

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

[PATCH v2 09/10] atheros eth: set addr_assign_type if random_ether_addr() used

[Danny Kukawka]

Set addr_assign_type correctly to NET_ADDR_RANDOM in case
a random MAC address was generated and assigned to the netdevice.

Fix error handling in atl1c_probe(). If atl1c_read_mac_addr()
couldn't get the hw mac address, and a random mac address get
set return the error code. Don't go to err_eeprom in
atl1c_probe(), use the generated MAC address in this case.

Reset the state to NET_ADDR_PERM as soon as the MAC get
changed via .ndo_set_mac_address.

v2: use bitops

Please don't shit up the comments:

> -	/* set a random MAC now in case platform_data doesn't provide one */
 ...
> +			/*set a random MAC since no valid provided by platform_data*/

You had to work to make that comment look worse than it originally
did in the code, spaces around the sentence and if you can be so
bothered capitalize sentences and put proper punctionation at the
end.

I took care of this, but I will not next time.

More bad comment formatting.

Again, I fixed it up but I will not next time.

Trailing whitespace.  This isn't something you need to be a rocket

This patch doesn't apply at all to the current net-next tree,
please always validate that your patches actually apply to the

Applied, but more coding style problems:

Come on, "if[SPACE](..." always.

Trailing whitespace.

Thanks. I fixed it but accidently send the unfixed version of the patches 
without noticing. Sorry.
