3c59x: fix PCI resource management

2013-05-30T13:35:13+00:00

[ Upstream commit 4b264a1676e70dc656ba53a8cac690f2d4b65f4e ]

The driver wrongly claimed I/O ports at an address returned by pci_iomap() --
even if it was passed an MMIO address.  Fix this by claiming/releasing all PCI
resources in the PCI driver's probe()/remove() methods instead and get rid of
'must_free_region' flag weirdness (why would Cardbus claim anything for us?).

3c59x: fix freeing nonexistent resource on driver unload

2013-05-30T13:35:13+00:00

[ Upstream commit c81400be716aa4c76f6ebf339ba94358dbbf6da6 ]

When unloading the driver that drives an EISA board, a message similar to the
following one is displayed:

Trying to free nonexistent resource <0000000000013000-000000000001301f>

Then an user is unable to reload the driver because the resource it requested in
the previous load hasn't been freed. This happens most probably due to a typo in
vortex_eisa_remove() which calls release_region() with 'dev->base_addr'  instead
of 'edev->base_addr'...

3c509.c: call SET_NETDEV_DEV for all device types (ISA/ISAPnP/EISA)

2013-05-30T13:35:12+00:00

[ Upstream commit 3b54912f9cd167641b91d4a697bd742f70e534fe ]

The venerable 3c509 driver only sets its device parent in one case, the ISAPnP one.
It does this with the SET_NETDEV_DEV function. It should register with the device
hierarchy in two additional cases: standard (non-PnP) ISA and EISA.

- Currently they appear here:
/sys/devices/virtual/net/eth0 (standard ISA)
/sys/devices/virtual/net/eth1 (EISA)

- Rather, they should instead be here:
/sys/devices/isa/3c509.0/net/eth0 (standard ISA)
/sys/devices/pci0000:00/0000:00:07.0/00:04/net/eth1 (EISA)

Tested on ISA and EISA boards.

3c59x: shorten timer period for slave devices

2012-03-01T00:30:57+00:00

[ Upstream commit 3013dc0cceb9baaf25d5624034eeaa259bf99004 ]

Jean Delvare reported bonding on top of 3c59x adapters was not detecting
network cable removal fast enough.

3c59x indeed uses a 60 seconds timer to check link status if carrier is
on, and 5 seconds if carrier is off.

This patch reduces timer period to 5 seconds if device is a bonding
slave.

net: add skb frag size accessors

2011-10-19T07:10:46+00:00

To ease skb->truesize sanitization, its better to be able to localize
all references to skb frags size.

Define accessors : skb_frag_size() to fetch frag size, and
skb_frag_size_{set|add|sub}() to manipulate it.

net: Remove unnecessary driver assignments of ethtool_ringparam fields to zero

2011-10-07T23:13:28+00:00

Per comments from Ben Hutchings on a previous patch, sweep the floors
a little removing unnecessary assignments of zero to fields of struct
ethtool_ringparam in driver code supporting ethtool -g.

MII: fix Kconfig dependencies for MII

2011-09-15T19:49:08+00:00

MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well.  It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled.  This caused a dependency error.

Resolved the dependency by selecting NET_CORE when MII is
selected.
