mlx4_en: fix allocation of CPU affinity reverse-map

2013-02-28T13:38:41+00:00

[ Upstream commit 3770699675dd1b8fc1e86ff369eb3cce44e10082 ]

The mlx4_en driver allocates the number of objects for the CPU affinity
reverse-map based on the number of rx rings of the device. However,
mlx4_assign_eq() calls irq_cpu_rmap_add() as many times as IRQ's are
assigned to EQ's, which can be as large as mlx4_dev->caps.comp_pool. If
caps.comp_pool is larger than rx_ring_num we will eventually hit the
BUG_ON() in cpu_rmap_add().

Fix this problem by allocating space for the maximum number of CPU
affinity reverse-map objects we might want to add.

mlx4_en: fix allocation of device tx_cq

2013-02-28T13:38:41+00:00

[ Upstream commit 427a96252d8eee7b9bbafce15bd37fa3387ede55 ]

The memory to hold the network device tx_cq is not being allocated with
the correct size in mlx4_en_init_netdev(). It should use MAX_TX_RINGS
instead of MAX_RX_RINGS. This can cause problems if the number of tx
rings being used is greater than MAX_RX_RINGS.

net/macb: fix race with RX interrupt while doing NAPI

2013-02-13T18:34:10+00:00

When interrupts are disabled, an RX condition can occur but
it is not reported when enabling interrupts again. We need to check
RSR and use napi_reschedule() if condition is met.

atl1c: add error checking for pci_map_single functions

2013-02-13T18:32:37+00:00

it is reported that code hit DMA-API errors on 3.8-rc6+,
(see https://bugzilla.redhat.com/show_bug.cgi?id=908436, and
     https://bugzilla.redhat.com/show_bug.cgi?id=908550)

this patch just adds error handler for
    pci_map_single and skb_frag_dma_map.

ixgbe: Only set gso_type to SKB_GSO_TCPV4 as RSC does not support IPv6

2013-02-12T21:07:19+00:00

The original fix that was applied for setting gso_type required more change
than necessary because it was assumed ixgbe does RSC on IPv6 frames and this
is not correct.  RSC is only supported with IPv4/TCP frames only.  As such we
can simplify the fix and avoid the unnecessary move of eth_type_trans.

The previous patch "ixgbe: fix gso type" and this patch reduce the entire fix
to one line that sets gso_type to TCPV4 if the frame is RSC.

bnx2x: set gso_type

2013-02-11T01:14:13+00:00

In LRO mode, bnx2x set gso_size but not gso type.
This leads to crashes in macvtap.
Commit cbf1de72324a8105ddcc3d9ce9acbc613faea17e
queued for 3.9 includes a more complete fix.
This is a minimal patch to avoid the crash, for 3.8.

stmmac: mdio register has to fail if the phy is not found

is not found; w/o this fix the mdio can be register twice when
do down/up the iface and this is not correct.
