3c59x: fix PCI resource management

2013-05-19T18:38:37+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

2013-05-19T18:38:37+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)

2013-05-19T18:38:34+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.

Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Bring in the 'net' tree so that we can get some ipv4/ipv6 bug
fixes that some net-next work will build upon.

drivers/net: delete old 8bit ISA 3c501 driver.

2013-01-22T15:39:49+00:00

It was amusing that linux was able to make use of this 1980's
technology on machines long past its intended lifespan, but
it probably should go now.

To set some context, the 3c501 was designed in the 1980's to be
used on 8088 PC-XT 8bit ISA machines.  It was built using a large
number of discrete TTL components and truly looks like a relic
of the ancient past before large scale integration was common.

But from a functional point of view, the real issue, as stated
in the (also obsolete) Ethernet-HowTo, is that "...the 3c501 can
only do one thing at a time -- while you are removing one packet
from the single-packet buffer it cannot receive another packet,
nor can it receive a packet while loading a transmit packet."

You know things are not good when the Kconfig help text suggests
you make a cron job doing a ping every minute.

Hardware that old and crippled is simply not going to be used by
anyone in a time where 10 year old 100Mbit PCI cards (that are
still functional) are largely give-away items.

3c574_cs: fix operator precedence between << and &

2013-01-17T20:04:30+00:00

The code to print the FIFO size in tc574_config computes it as:

  8 << config & Ram_size

which evaluates the '<<' first, but the actual intent is to evaluate the
'&' first.  Add parentheses to enforce desired evaluation order.

remove init of dev->perm_addr in drivers

2013-01-09T02:00:48+00:00

perm_addr is initialized correctly in register_netdevice() so to init it in
drivers is no longer needed.

drivers/net: remove orphaned references to micro channel

2013-01-07T05:13:33+00:00

We threw away the microchannel support, but the removal wasn't
completely trivial since there was namespace overlap with the
machine check support, and hence some orphaned dependencies
survived the deletion.  This attempts to sweep those up and
send them to the bit-bucket.

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.

drivers/net: fix up function prototypes after __dev* removals

2012-12-07T19:22:22+00:00

The __dev* removal patches for the network drivers ended up messing up
the function prototypes for a bunch of drivers.  This patch fixes all of
them back up to be properly aligned.

Bonus is that this almost removes 100 lines of code, always a nice
surprise.
