e2f9ecfcc6 bna: use ether_addr_copy instead of memcpy
Parameters of all ether_addr_copy instances were checked for proper
alignment. Alignment of bnad_bcast_addr is forced to 2 as the implicit
alignment is 1.
I have also renamed address parameter of bnad_set_mac_address() to addr.
The name mac_addr was a little bit confusing as the real parameter is
struct sockaddr *.

v2: added __aligned directive to bnad_bcast_addr, renamed parameter of
    bnad_set_mac_address() (thx joe@perches.com)

56508b5013 net/mlx5_core: Add transport domain alloc/dealloc support
Each transport object, namely TIR and TIS, must have a transport domain
number (TDN) identifier.

The driver wrongly assumed that it is OK to use TDN=0 without explicit
TDN allocation from the device.

The TDN will also be used for isolating different processes once user
mode Ethernet will be supported.

12be4b2190 net/mlx5e: Support NETIF_F_SG
When NETIF_F_SG is set, each send WQE may have a different size since
each skb can have different number of fragments as of LSO header etc.

This implies that a given WQE may wrap around the send queue, i.e begin
at its end and continue at its start. While it is legal by the device spec,
we preferred a solution that avoids it - when building of current WQE is
done, if the next WQE may wrap around the send queue, fill the send queue
with NOPs WQEs till its end, so that the next WQE will begin at send queue
start.

NOP WQE for itself cannot wrap around the send queue since it is of
minimal size - 64 bytes, and all send WQEs are a multiple of that size.

7161d18f66 net/ps3_gelic: Fix build error with DEBUG
When the DEBUG preprocessor macro is defined the ps3_gelic_net driver build
fails due to an undeclared routine gelic_descr_get_status().  This problem
was introduced during the code cleanup of commit
6b0c21cede22be1f68f0a632c0ca38008ce1abe7 (net: Fix p3_gelic_net sparse warnings),
which re-arranged the ordering of some of the gelic routines.

This change just moves the gelic_descr_get_status() routine up in the
ps3_gelic_net.c source file. There is no functional change.

Fixes build errors like these:

9d3366e95d net: bcmgenet: handle broken turn-around for specific PHYs
Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware
bug which makes them not release the MDIO line during turn-around time.
This gets flagged by the GENET MDIO controller as a read failure, and we
fail the read transaction.

Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading
from and if it is listed in this bitmask, ignore the read failure and
proceed with returning the data we read out of the controller.

a0d2f20650 Renesas Ethernet AVB PTP clock driver
Ethernet AVB device includes the gPTP  timer, so we can implement a PTP clock
driver.  We're doing that in a separate file, with  the main Ethernet driver
calling the PTP driver's [de]initialization and interrupt handler functions.
Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that
one leaves the operation mode, we have to unregister the PTP clock... :-(

c156633f13 Renesas Ethernet AVB driver proper
Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically
compatible with SuperH Gigabit Ethernet E-MAC.  Ethernet AVB has  a  dedicated
direct memory access controller (AVB-DMAC) that is a new design compared to the
SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE
802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-
time transfer, and the IEEE 802.1Qat stream reservation protocol.

The  driver only supports device tree probing, so the binding document is
included in this patch.

8b13b4e0bc enic: fix memory leak in rq_clean
When incoming packet qualifies for rx_copybreak, we copy the data to newly
allocated skb. We do not free/unmap the original buffer. At this point driver
assumes this buffer is unallocated. When enic_rq_alloc_buf() is called for
buffer allocation, it checks if buf->os_buf is NULL. If its not NULL that means
buffer can be re-used.

When vnic_rq_clean() is called for freeing all rq buffers, and if the
rx_copybreak reused buffer falls outside the used desc, we do not free the
buffer. The following trace is observer when dma-debug is enabled.

Fix is to walk through complete ring and clean if buffer is present.

====================
Intel Wired LAN Driver Updates 2015-06-09

This series contains updates to ixgbe only.

The series adds additional support for x550 support, such as WoL and
auto-negotiation of flow control.  Adds new PHY support (external PHY)
for x550, as well as the new methods/functions needed to support the new
PHY's.  Fixed a bug found in code inspection, where a check was missed
when clearing counters for x550.  Also fixed the init code flow for copper
x550 devices.

e2261bcc2a ixgbe: fix X550 devices init flow
Reviewing the X550 copper init flow with the Si team resulted in a
new simplified flow.  We no longer wait for the PHY FW initialization
complete bit to be set as this bit is only set once by the PHY at power
on and then cleared on the first read. So only the first instance of
running SW (or possibly MAC FW) needs to initialize the PHY.

The PHY initialization has been simplified and now only requires that
the PHY FW be un-stalled
low-power mode or enabled the transceiver

c3dc4c09f1 ixgbe: add X550 support for external PHY and forced 1G/10G support
This patch adds x550 external PHY interrupt and forced 1G/10G support.
This included enabling and handling LSC and thermal sensor interrupt.
ixgbe_handle_lasi() has been added for handling the interrupts received
over SDP0 from the external 10baseT PHY. ixgbe_enable_lasi_ext_t_x550em
and ixgbe_get_lasi_ext_t_x550em have been added to X550em to enable
mask and check interrupt flags for the external PHY.

Forced 1G/10G link speed is handled via ixgbe_mac_link_t_X550em.
ixgbe_seupt_mac_link_t_X550em sets up the internal PHY and external PHY
to either iXFI (10G) or KX (1G) based on the user selected auto
advertised link speed setting. Then sets up the external PHY auto
advertised link speed.
