TJA1102 is a dual PHY package with PHY0 having proper PHYID and PHY1
having no ID. On one hand it is possible to for PHY detection by
compatible, on other hand we should be able to reset complete chip
before PHY1 configured it, and we need to define dependencies for proper
power management.
We can solve it by defining PHY1 as child of PHY0:
tja1102_phy0: ethernet-phy@4 {
reg = <0x4>;
interrupts-extended = <&gpio5 8 IRQ_TYPE_LEVEL_LOW>;
reset-gpios = <&gpio5 9 GPIO_ACTIVE_LOW>;
reset-assert-us = <20>;
reset-deassert-us = <2000>;
tja1102_phy1: ethernet-phy@5 {
reg = <0x5>;
interrupts-extended = <&gpio5 8 IRQ_TYPE_LEVEL_LOW>;
};
};
The PHY1 should be a subnode of PHY0 and registered only after PHY0 was
completely reset and initialized.

Add support for following phy-modes: rgmii, rgmii-id, rgmii-txid, rgmii-rxid.
This PHY has an internal RX delay of 1.2ns and no delay for TX.
The pad skew registers allow to set the total TX delay to max 1.38ns and
the total RX delay to max of 2.58ns (configurable 1.38ns + build in
1.2ns) and a minimal delay of 0ns.
According to the RGMII v1.3 specification the delay provided by PCB traces
should be between 1.5ns and 2.0ns. The RGMII v2.0 allows to provide this
delay by MAC or PHY. So, we configure this PHY to the best values we can
get by this HW: TX delay to 1.38ns (max supported value) and RX delay to
1.80ns (best calculated delay)
The phy-modes can still be fine tuned/overwritten by *-skew-ps
device tree properties described in:

sctp: Fix problems with peer restart when in SHUTDOWN-PENDING state and socket is closed
These patches are related to the scenario described in commit
bdf6fa52f0 ("sctp: handle association restarts when the socket is
closed."). To recap, when our association is in SHUTDOWN-PENDING state
and we've closed our one-to-one socket, while the peer crashes without
being detected, restarts and reconnects using the same addresses and
ports, we start association shutdown.
In this case, Cumulative TSN Ack in the SHUTDOWN that we send has
always been incorrect. Additionally, bundling of the SHUTDOWN with the
COOKIE-ACK was broken by a later commit. This series fixes both of
these issues.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
When starting shutdown in sctp_sf_do_dupcook_a(), get the value for
SHUTDOWN Cumulative TSN Ack from the new association, which is
reconstructed from the cookie, instead of the old association, which
the peer doesn't have anymore.
Otherwise the SHUTDOWN is either ignored or replied to with an ABORT
by the peer because CTSN Ack doesn't match the peer's Initial TSN.

When we start shutdown in sctp_sf_do_dupcook_a(), we want to bundle
the SHUTDOWN with the COOKIE-ACK to ensure that the peer receives them
at the same time and in the correct order. This bundling was broken by
commit 4ff40b8626 ("sctp: set chunk transport correctly when it's a
new asoc"), which assigns a transport for the COOKIE-ACK, but not for
the SHUTDOWN.
Fix this by passing a reference to the COOKIE-ACK chunk as an argument
to sctp_sf_do_9_2_start_shutdown() and onward to
sctp_make_shutdown(). This way the SHUTDOWN chunk is assigned the same
transport as the COOKIE-ACK chunk, which allows them to be bundled.
In sctp_sf_do_9_2_start_shutdown(), the void *arg parameter was
previously unused. Now that we're taking it into use, it must be a
valid pointer to a chunk, or NULL. There is only one call site where
it's not, in sctp_sf_autoclose_timer_expire(). Fix that too.

Right now it can be seen that the VSC9959 (Felix) switch will not flood
frames if they have a VLAN tag with a PCP of 1-7 (nonzero).
It turns out that Felix is quite different from its cousin, Ocelot, in
that frame flooding can be allowed/denied per traffic class. Where
Ocelot has 1 instance of the ANA_FLOODING register, Felix has 8.
The approach that this driver is going to take is "thanks, but no
thanks". We have no use case of limiting the flooding domain based on
traffic class, so we just want to allow packets to be flooded, no matter
what traffic class they have.
So we copy the line of code from ocelot.c which does the one-shot
initialization of the flooding PGIDs, and we add it to felix.c as well -
except replicated 8 times.

As the bug report [1] pointed out, <linux/vermagic.h> must be included
after <linux/module.h>.
I believe we should not impose any include order restriction. We often
sort include directives alphabetically, but it is just coding style
convention. Technically, we can include header files in any order by
making every header self-contained.
Currently, arch-specific MODULE_ARCH_VERMAGIC is defined in
<asm/module.h>, which is not included from <linux/vermagic.h>.
Hence, the straight-forward fix-up would be as follows:
|--- a/include/linux/vermagic.h
|+++ b/include/linux/vermagic.h
|@@ -1,5 +1,6 @@
| /* SPDX-License-Identifier: GPL-2.0 */
| #include <generated/utsrelease.h>
|+#include <linux/module.h>
|
| /* Simply sanity version stamp for modules. */
| #ifdef CONFIG_SMP
This works enough, but for further cleanups, I split MODULE_ARCH_VERMAGIC
definitions into <asm/vermagic.h>.
With this, <linux/module.h> and <linux/vermagic.h> will be orthogonal,
and the location of MODULE_ARCH_VERMAGIC definitions will be consistent.
For arc and ia64, MODULE_PROC_FAMILY is only used for defining
MODULE_ARCH_VERMAGIC. I squashed it.
For hexagon, nds32, and xtensa, I removed <asm/modules.h> entirely
because they contained nothing but MODULE_ARCH_VERMAGIC definition.
Kbuild will automatically generate <asm/modules.h> at build-time,
wrapping <asm-generic/module.h>.

This patch is basically fixing the lookup of tcons (DFS specific) during
reconnect (smb2pdu.c:__smb2_reconnect) to update their prefix paths.
Previously, we relied on the TCP_Server_Info pointer
(misc.c:tcp_super_cb) to determine which tcon to update the prefix path
We could not rely on TCP server pointer to determine which super block
to update the prefix path when reconnecting tcons since it might map
to different tcons that share same TCP connection.
Instead, walk through all cifs super blocks and compare their DFS full
paths with the tcon being updated to.

This disables tcon re-use for DFS shares.
tcon->dfs_path stores the path that the tcon should connect to when
doing failing over.
If that tcon is used multiple times e.g. 2 mounts using it with
different prefixpath, each will need a different dfs_path but there is
only one tcon. The other solution would be to split the tcon in 2
tcons during failover but that is much harder.
tcons could not be shared with DFS in cifs.ko because in a
DFS namespace like:
//domain/dfsroot -> /serverA/dfsroot, /serverB/dfsroot
//serverA/dfsroot/link -> /serverA/target1/aa/bb
//serverA/dfsroot/link2 -> /serverA/target1/cc/dd
you can see that link and link2 are two DFS links that both resolve to
the same target share (/serverA/target1), so cifs.ko will only contain a
single tcon for both link and link2.
The problem with that is, if we (auto)mount "link" and "link2", cifs.ko
will only contain a single tcon for both DFS links so we couldn't
perform failover or refresh the DFS cache for both links because
tcon->dfs_path was set to either "link" or "link2", but not both --
which is wrong.
