net: bcmgenet: use MAC link status for fixed phy

2018-09-15T07:40:37+00:00

[ Upstream commit c3c397c1f16c51601a3fac4fe0c63ad8aa85a904 ]

When using the fixed PHY with GENET (e.g. MOCA) the PHY link
status can be determined from the internal link status captured
by the MAC. This allows the PHY state machine to use the correct
link state with the fixed PHY even if MAC link event interrupts
are missed when the net device is opened.

bnx2x: Fix invalid memory access in rss hash config path.

2018-09-05T07:18:35+00:00

[ Upstream commit ae2dcb28c24794a87e424a726a1cf1a61980f52d ]

Rx hash/filter table configuration uses rss_conf_obj to configure filters
in the hardware. This object is initialized only when the interface is
brought up.
This patch adds driver changes to configure rss params only when the device
is in opened state. In port disabled case, the config will be cached in the
driver structure which will be applied in the successive load path.

Please consider applying it to 'net' branch.

bnxt_en: Fix for system hang if request_irq fails

[ Upstream commit c58387ab1614f6d7fb9e244f214b61e7631421fc ]

Fix bug in the error code path when bnxt_request_irq() returns failure.
bnxt_disable_napi() should not be called in this error path because
NAPI has not been enabled yet.

bnx2x: Fix receiving tx-timeout in error or recovery state.

2018-08-24T11:26:57+00:00

[ Upstream commit 484c016d9392786ce5c74017c206c706f29f823d ]

Driver performs the internal reload when it receives tx-timeout event from
the OS. Internal reload might fail in some scenarios e.g., fatal HW issues.
In such cases OS still see the link, which would result in undesirable
functionalities such as re-generation of tx-timeouts.
The patch addresses this issue by indicating the link-down to OS when
tx-timeout is detected, and keeping the link in down state till the
internal reload is successful.

Please consider applying it to 'net' branch.

bcm63xx_enet: do not write to random DMA channel on BCM6345

2018-07-22T12:25:52+00:00

commit d6213c1f2ad54a964b77471690264ed685718928 upstream.

The DMA controller regs actually point to DMA channel 0, so the write to
ENETDMA_CFG_REG will actually modify a random DMA channel.

Since DMA controller registers do not exist on BCM6345, guard the write
with the usual check for dma_has_sram.

bnx2x: use the right constant

[ Upstream commit dd612f18a49b63af8b3a5f572d999bdb197385bc ]

Nearby code that also tests port suggests that the P0 constant should be
used when port is zero.

The semantic match that finds this problem is as follows:
