2012-04-13T15:33:50+00:00

commit a2daf263107ba3eb6db33931881731fa51c95045 upstream.

Added Vendor/Device Id of Motorola Rokr E6 (22b8:6027) so it can be

r8169: runtime resume before shutdown.

2012-04-13T15:33:48+00:00

commit 2a15cd2ff488a9fdb55e5e34060f499853b27c77 upstream.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.

Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.

Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.

rtlwifi: rtl8192ce: rtl8192cu: rtl8192de: Fix low-gain setting when scanning

2012-04-13T15:33:47+00:00

commit 643c61e119459e9d750087b7b34be94491efebf9 upstream.

In https://bugzilla.redhat.com/show_bug.cgi?id=770207, slowdowns of driver
rtl8192ce are reported. One fix (commit a9b89e2) has already been applied,
and it helped, but the maximum RX speed would still drop to 1 Mbps. As in
the previous fix, the initial gain was determined to be the problem; however,
the problem arises from a setting of the gain when scans are started.

Driver rtl8192de also has the same code structure - this one is fixed as well.

Fix non TBI PHY access; a bad merge undid bug fix in a previous commit.

2012-04-13T15:33:45+00:00

[ Upstream commit 464b57da56910c8737ede75ad820b9a7afc46b3e ]

The merge done in commit b26e478f undid bug fix in commit c3e072f8
("net: fsl_pq_mdio: fix non tbi phy access"), with the result that non
TBI (e.g. MDIO) PHYs cannot be accessed.

net: usb: cdc_eem: fix mtu

2012-04-13T15:33:45+00:00

[ Upstream commit 78fb72f7936c01d5b426c03a691eca082b03f2b9 ]

Make CDC EEM recalculate the hard_mtu after adjusting the
hard_header_len.

Without this, usbnet adjusts the MTU down to 1494 bytes, and the host is
unable to receive standard 1500-byte frames from the device.

Tested with the Linux USB Ethernet gadget.

If port 0 of a 5717 serdes device powers down, it hides the phy from

sky2: override for PCI legacy power management

[ Upstream commit 5676cc7bfe1e388e87843f71daa229610385b41e ]

Some BIOS's don't setup power management correctly (what else is
new) and don't allow use of PCI Express power control. Add a special
exception module parameter to allow working around this issue.
Based on slightly different patch by Knut Petersen.

e1000e: Avoid wrong check on TX hang

2012-04-02T16:52:52+00:00

commit 09357b00255c233705b1cf6d76a8d147340545b8 upstream.

Based on the original patch submitted my Michael Wang
.
Descriptors may not be write-back while checking TX hang with flag
FLAG2_DMA_BURST on.
So when we detect hang, we just flush the descriptor and detect
again for once.

-v2 change 1 to true and 0 to false and remove extra ()

usbnet: don't clear urb->dev in tx_complete

2012-04-02T16:52:51+00:00

commit 5d5440a835710d09f0ef18da5000541ec98b537a upstream.

URB unlinking is always racing with its completion and tx_complete
may be called before or during running usb_unlink_urb, so tx_complete
must not clear urb->dev since it will be used in unlink path,
otherwise invalid memory accesses or usb device leak may be caused
inside usb_unlink_urb.
