net: phy: at803x device tree binding
Adds a device tree binding to configure the clock and the RGMII voltage.
Changes since v1:
- rebased to latest net-next
- renamed "Atheros" to "Qualcomm Atheros"
- add a new patch to remove config_init() from AR9331
Changes since the RFC:
- renamed the Kconfig entry to "Qualcomm Atheros.." and reordered the
item
- renamed the prefix from atheros to qca
- use the correct name AR803x (instead of AT803x) in new files and
dt-bindings.
- listed the PHY maintainers in the new schema. Hopefully, thats ok.
- fixed a typo in the bindings schema
- run dtb_checks and dt_binding_check and fixed the schema
- dropped the rgmii-io-1v8 property; instead provide two regulators vddh
and vddio, add one consumer vddio-supply
- fix the clock settings for the AR8030/AR8035
- only the AR8031 supports chaning the LDO and the PLL mode in software.
Check if we have the correct PHY.
- new patch to mention the AR8033 which is the same as the AR8031 just
without PTP support
- new patch which corrects any displayed PHY names and comments. Be
consistent.

When preparing tunnel packets for the link failover or synchronization,
as for the safe algorithm, we added a dummy packet on the pair link but
never sent it out. In the case of failover, the pair link will be reset
anyway. But for link synching, it will always result in retransmission
of the dummy packet after that.
We have also observed that such the retransmission at the early stage
when a new node comes in a large cluster will take some time and hard
to be done, leading to the repeated retransmit failures and the link is
reset.
Since in commit 4929a932be ("tipc: optimize link synching mechanism")
we have already built a dummy 'TUNNEL_PROTOCOL' message on the new link
for the synchronization, there's no need for the dummy on the pair one,
this commit will skip it when the new mechanism takes in place. In case
nothing exists in the pair link's transmq, the link synching will just
start and stop shortly on the peer side.
The patch is backward compatible.

Until now the size of a Rx buffer was artificially limited
to 1536B (which happens to be the default, after reset, hardware
value for a Rx buffer). This approach however leaves unused
memory space for Rx packets, since the driver uses a paged
allocation scheme that reserves half a page for each Rx skb.
There's also the inconvenience that frames around 1536 bytes
can get scattered if the limit is slightly exceeded. This limit
can be exceeded even for standard MTU of 1500B traffic, for common
cases like stacked VLANs, or DSA tags.
To address these issues, let's just compute the buffer size
starting from the upper limit of 2KB (half a page) and
subtract the skb overhead and alignment restrictions.

("igb: flush when in xmit_more mode and under descriptor pressure") and
commit 6b16f9ee89 ("net: move skb->xmit_more hint to softnet data") that
were made to igb to support this feature. The function netif_xmit_stopped
is called to check whether transmit queue on device is currently unable to
send to determine whether we must write the tail because we can add no
further buffers.
When normal packets and/or xmit_more packets fill up tx_desc, it is
necessary to trigger NIC tx reg.
Following the advice from David Miller and Jakub Kicinski, after the
xmit_more feature is added, the following scenario will occur.
|
xmit_more packets
|
DMA_MAPPING
|
DMA_MAPPING error check
|
xmit_more packets already in HW xmit queue
|
In the above scenario, if DMA_MAPPING error occurrs, the xmit_more packets
already in HW xmit queue will also be dropped. This is different from the
behavior before xmit_more feature. So it is necessary to trigger NIC HW tx
reg in the above scenario.
To the non-xmit_more packets, the above scenario will not occur.
