net: sh_eth: fix incorrect RX length error if R8A7740

2013-06-27T17:39:07+00:00

[ Upstream commit dd019897358b815f7828dab90b51d51df4d3658d ]

This patch fixes an issue that the driver increments the "RX length error"
on every buffer in sh_eth_rx() if the R8A7740.
This patch also adds a description about the Receive Frame Status bits.

8139cp: reset BQL when ring tx ring cleared

2013-06-27T17:38:48+00:00

[ Upstream commit 98962baad72fd6d393bf39dbb7c2076532c363c6 ]

This patch cures transmit timeout's with DHCP observed
while running under KVM. When the transmit ring is cleaned out,
the Byte Queue Limit values need to be reset.

r8169: fix offloaded tx checksum for small packets.

2013-06-27T17:38:48+00:00

[ Upstream commit b423e9ae49d78ea3f53b131c8d5a6087aed16fd6 ]

8168evl offloaded checksums are wrong since commit
e5195c1f31f399289347e043d6abf3ffa80f0005 ("r8169: fix 8168evl frame padding.")
pads small packets to 60 bytes (without ethernet checksum). Typical symptoms
appear as UDP checksums which are wrong by the count of added bytes.

It isn't worth compensating. Let the driver checksum.

Due to the skb length changes, TSO code is moved before the Tx descriptor gets
written.

net: fec: fix kernel oops when plug/unplug cable many times

2013-06-27T17:38:46+00:00

[ Upstream commits 54309fa60b5f57b90c1842176f6045e665d21142 and
  3169134478a9638baf0dbb4fdca5a0718cbe8e27 ]

reproduce steps
 1. flood ping from other machine
 	ping -f -s 41000 IP
 2. run below script
    while [ 1 ]; do ethtool -s eth0 autoneg off;
    sleep 3;ethtool -s eth0 autoneg on; sleep 4; done;

You can see oops in one hour.

The reason is fec_restart clear BD but NAPI may use it.
The solution is disable NAPI and stop xmit when reset BD.
disable NAPI may sleep, so fec_restart can't be call in
atomic context.

tg3: Wait for boot code to finish after power on

2013-06-20T19:01:38+00:00

commit df465abfe06f7dc4f33f4a96d17f096e9e8ac917 upstream.

Some systems that don't need wake-on-lan may choose to power down the
chip on system standby. Upon resume, the power on causes the boot code
to startup and initialize the hardware. On one new platform, this is
causing the device to go into a bad state due to a race between the
driver and boot code, once every several hundred resumes. The same race
exists on open since we come up from a power on.

This patch adds a wait for boot code signature at the beginning of
tg3_init_hw() which is common to both cases. If there has not been a
power-off or the boot code has already completed, the signature will be
present and poll_fw() returns immediately. Also return immediately if
the device does not have firmware.

tg3: Add read dma workaround for 5720

commit 9bc297ea0622bb2a6b3abfa2fa84f0a3b86ef8c8 upstream.

Commit 091f0ea30074bc43f9250961b3247af713024bc6 "tg3: Add New 5719 Read
DMA workaround" added a workaround for TX DMA stall on the 5719. This
workaround needs to be applied to the 5720 as well.

tg3: Fix data corruption on 5725 with TSO

commit 0f0d15100a8ac875bdd408324c473e16d73d3557 upstream.

The 5725 family of devices (asic rev 5762), corrupts TSO packets where
the buffer is within MSS bytes of a 4G boundary (4G, 8G etc.). Detect
this condition and trigger the workaround path.

tg3: Skip powering down function 0 on certain serdes devices

commit 44f3b503c16425c8e9db4bbaa2fc9cd0c9d0ba91 upstream.

On the 5718, 5719 and 5720 serdes devices, powering down function 0
results in all the other ports being powered down. Add code to skip
function 0 power down.

v2:
 - Modify tg3_phy_power_bug() function to use a switch instead of a
   complicated if statement. Suggested by Joe Perches.

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?).
