2011-10-24be2net: don't create multiple TXQs in BE2Sathya Perla1-10/+16

2011-10-24be2net: refactor VF setup/teardown code into be_vf_setup/clear()Sathya Perla3-152/+147
Currently the code for VF setup/teardown done by a PF (if_create, mac_add_config, link_status_query etc) is scattered; this patch refactors this code into be_vf_setup() and be_vf_clear(). The if_create/if_destroy/mac_addr_query cmds are now called after the MCCQ is created; so these cmds are now modified to use the MCCQ instead of MBOX.

2011-10-24be2net: add vlan/rx-mode/flow-control config to be_setup()Sathya Perla1-65/+56
When a card is reset due to EEH error recovery or due to a suspend, rx-mode config (promisc/mc) is not being sent to the FW. be_setup() is called in these flows and is the best place for such config/re-config cmds. Hence include rx-mode, vlan and flow-control config in be_setup(). Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-24jme: fix irq storm after suspend/resumeClemens Buchacher1-0/+6
If the device is down during suspend/resume, interrupts are enabled without a registered interrupt handler, causing a storm of unhandled interrupts until the IRQ is disabled because "nobody cared".

2011-10-21macvtap: Fix the minor device number allocationEric W. Biederman1-16/+71
On systems that create and delete lots of dynamic devices the 31bit linux ifindex fails to fit in the 16bit macvtap minor, resulting in unusable macvtap devices. I have systems running automated tests that that hit this condition in just a few days. Use a linux idr allocator to track which mavtap minor numbers are available and and to track the association between macvtap minor numbers and macvtap network devices. Remove the unnecessary unneccessary check to see if the network device we have found is indeed a macvtap device. With macvtap specific data structures it is impossible to find any other kind of networking device. Increase the macvtap minor range from 65536 to the full 20 bits that is supported by linux device numbers. It doesn't solve the original problem but there is no penalty for a larger minor device range. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S.

To see if it is appropriate to enable the macvtap zero copy feature don't test the lowerdev network device flags. Instead test the macvtap network device flags which are a direct copy of the lowerdev flags.

2011-10-21macvtap: Close a race between macvtap_open and macvtap_dellink.Eric W. Biederman1-0/+2
There is a small window in macvtap_open between looking up a networking device and calling macvtap_set_queue in which macvtap_del_queues called from macvtap_dellink. After calling macvtap_del_queues it is totally incorrect to allow macvtap_set_queue to proceed so prevent success by reporting that all of the available queues are in use. Signed-off-by: Eric W.

2011-10-19stmmac: add CHAINED descriptor mode support (V4)Giuseppe CAVALLARO10-105/+491
This patch enhances the STMMAC driver to support CHAINED mode of descriptor. STMMAC supports DMA descriptor to operate both in dual buffer(RING) and linked-list(CHAINED) mode. In RING mode (default) each descriptor points to two data buffer pointers whereas in CHAINED mode they point to only one data buffer pointer. In CHAINED mode each descriptor will have pointer to next descriptor in the list, hence creating the explicit chaining in the descriptor itself, whereas such explicit chaining is not possible in RING mode. First version of this work has been done by Rayagond. Then the patch has been reworked avoiding ifdef inside the C code. A new header file has been added to define all the functions needed for managing enhanced and normal descriptors. In fact, these have to be specialized according to the ring/chain usage. Two new C files have been also added to implement the helper routines needed to manage: jumbo frames, chain and ring setup (i.e. desc3).

The port shouldn't be enabled unless its current MUX state is DISTRIBUTING which is correctly handled by ad_mux_machine(), otherwise the packet sent can be lost because the other end may not be ready. The issue happens on every port initialization, but as the ports are expected to move quickly to DISTRIBUTING, it doesn't cause much problem. However, it does cause constant packet loss if the other peer has the port configured to stay in STANDBY (i.e. SYNC set to OFF). Signed-off-by: Flavio Leitner <fbl@redhat.com> Signed-off-by: David S.

2011-10-19r8169: fix driver shutdown WoL regression.françois romieu1-32/+56
Due to commit 92fc43b4159b518f5baae57301f26d770b0834c9 ("r8169: modify the flow of the hw reset."), rtl8169_hw_reset stomps during driver shutdown on RxConfig bits which are needed for WOL on some versions of the hardware. As these bits were formerly set from the r81{0x, 68}_pll_power_down methods, factor them out for use in the driver shutdown (rtl_shutdown) handler. I favored __rtl8169_get_wol() -hardware state indication- over RTL_FEATURE_WOL as the latter has become a good candidate for removal.

2011-10-19phylib: Modify Vitesse RGMII skew settingsAndy Fleming1-12/+22
The Vitesse driver was using the RGMII_ID interface type to determine if skew was necessary. However, we want to move away from using that interface type, as it's really a property of the board's PHY connection. However, some boards depend on it, so we want to support it, while allowing new boards to use the more flexible "fixups" approach. To do this, we extract the code which adds skew into its own function, and call that function when RGMII_ID has been selected. Another side-effect of this change is that if your PHY has skew set already, it doesn't clear it. This way, the fixup code can modify the register without config_init then clearing it.

2011-10-19[media] videodev: fix a NULL pointer dereference in v4l2_device_release()Antonio Ospite1-1/+1
The change in 8280b66 does not cover the case when v4l2_dev is already NULL, fix that. With a Kinect sensor, seen as an USB camera using GSPCA in this context, a NULL pointer dereference BUG can be triggered by just unplugging the device after the camera driver has been loaded.
