net: dsa: inherit addr_assign_type along with dev_addr

2013-09-04T00:57:49+00:00

A device inheriting a random or set address should reflect this in
its addr_assign_type.

dsa: use an unique and non conflicting bus name for the slave MII bus

2013-01-21T20:40:11+00:00

The slave MII bus registered by the DSA code is using the parent MII bus
as part of its name (ds->master_mii_bus_id), in case the parent MII bus
name is already 16 characters long (such as d0072004.mdio-mi) we will
get the following WARN_ON in dsa_switch_setup() when calling
mdiobus_register():

[   79.088782] ------------[ cut here ]------------
[   79.093448] WARNING: at fs/sysfs/dir.c:536 sysfs_add_one+0x80/0xa0()
[   79.099831] sysfs: cannot create duplicate filename
'/class/mdio_bus/d0072004.mdio-mi'

This is a genuine warning, because the DSA slave MII bus will also be
named d0072004.mdio-mi, and since MII_BUS_ID_SIZE is 17 characters long
(with null-terminator) the following will truncate the slave MII bus id:

snprintf(ds->slave_mii_bus->id, MII_BUS_ID_SIZE, "%s-%d:%.2x",
                        ds->master_mii_bus->id, ds->pd->sw_addr);

Fix this by using dsa-: which is guaranteed to be
unique.

net: phy: remove flags argument from phy_{attach, connect, connect_direct}

2013-01-14T20:11:50+00:00

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

ethtool: fix drvinfo strings set in drivers

2013-01-07T05:06:31+00:00

Use strlcpy where possible to ensure the string is \0 terminated.
Use always sizeof(string) instead of 32, ETHTOOL_BUSINFO_LEN
and custom defines.
Use snprintf instead of sprint.
Remove unnecessary inits of ->fw_version
Remove unnecessary inits of drvinfo struct.

dsa: Convert compare_ether_addr to ether_addr_equal

2012-05-10T00:49:19+00:00

Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

net: preserve ifreq parameter when calling generic phy_mii_ioctl().

2010-07-19T02:15:25+00:00

The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
We need access to the ifreq in order to support PHYs that can perform
hardware time stamping.

Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
This is unnecessary since phylib will check the command in any case.

net: convert unicast addr list

2009-05-30T05:12:32+00:00

This patch converts unicast address list to standard list_head using
previously introduced struct netdev_hw_addr. It also relaxes the
locking. Original spinlock (still used for multicast addresses) is not
needed and is no longer used for a protection of this list. All
reading and writing takes place under rtnl (with no changes).

I also removed a possibility to specify the length of the address
while adding or deleting unicast address. It's always dev->addr_len.

The convertion touched especially e1000 and ixgbe codes when the
change is not so trivial.
