e1000e: Fix e1000_check_for_copper_link_ich8lan return value.

2018-01-17T08:35:32+00:00

commit 4110e02eb45ea447ec6f5459c9934de0a273fb91 upstream.

e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan()
are the two functions that may be assigned to mac.ops.check_for_link when
phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e:
Separate signaling for link check/link up") changed the meaning of the
return value of check_for_link for copper media but only adjusted the first
function. This patch adjusts the second function likewise.

net: stmmac: enable EEE in MII, GMII or RGMII only

2018-01-17T08:35:29+00:00

[ Upstream commit 879626e3a52630316d817cbda7cec9a5446d1d82 ]

Note in the databook - Section 4.4 - EEE :
" The EEE feature is not supported when the MAC is configured to use the
TBI, RTBI, SMII, RMII or SGMII single PHY interface. Even if the MAC
supports multiple PHY interfaces, you should activate the EEE mode only
when the MAC is operating with GMII, MII, or RGMII interface."

Applying this restriction solves a stability issue observed on Amlogic
gxl platforms operating with RMII interface and the internal PHY.

sh_eth: fix SH7757 GEther initialization

2018-01-17T08:35:29+00:00

[ Upstream commit 5133550296d43236439494aa955bfb765a89f615 ]

Renesas  SH7757 has 2 Fast and 2 Gigabit Ether controllers, while the
'sh_eth' driver can only reset and initialize TSU of the first controller
pair. Shimoda-san tried to solve that adding the 'needs_init' member to the
'struct sh_eth_plat_data', however the platform code still never sets this
flag. I think  that we can infer this information from the 'devno' variable
(set  to 'platform_device::id') and reset/init the Ether controller pair
only for an even 'devno'; therefore 'sh_eth_plat_data::needs_init' can be
removed...

sh_eth: fix TSU resource handling

2018-01-17T08:35:29+00:00

[ Upstream commit dfe8266b8dd10e12a731c985b725fcf7f0e537f0 ]

When switching  the driver to the managed device API,  I managed to break
the  case of a  dual Ether devices sharing a single TSU: the 2nd Ether port
wouldn't probe. Iwamatsu-san has tried to fix this but his patch was buggy
and he then dropped the ball...

The solution is to  limit calling devm_request_mem_region() to the first
of  the two  ports  sharing the same TSU, so devm_ioremap_resource() can't
be used anymore for the TSU resource...

cx82310_eth: use skb_cow_head() to deal with cloned skbs

2018-01-17T08:35:28+00:00

commit a9e840a2081ed28c2b7caa6a9a0041c950b3c37d upstream.

We need to ensure there is enough headroom to push extra header,
but we also need to check if we are allowed to change headers.

skb_cow_head() is the proper helper to deal with this.
