Due to a mistake, the driver always sets the address learning flag to
the previously stored value, and not to the currently configured one.
The bug is visible only in standalone ports mode, because when the port
is bridged, the issue is masked by .port_stp_state_set which overwrites
the address learning state to the proper value.

Some internal PHY's have their events like link change reported by the
MAC interrupt. We have PHY_IGNORE_INTERRUPT to deal with this scenario.
I'm not too happy with this name. We don't ignore interrupts, typically
there is no interrupt exposed at a PHY level. So let's rename it to
PHY_MAC_INTERRUPT. This is in line with phy_mac_interrupt(), which is
called from the MAC interrupt handler to handle PHY events.

The work queue is used to queue reset requests like CHANGE-PARAM or
FAILOVER resets for the worker thread. When the adapter is being removed
the adapter state is set to VNIC_REMOVING and the work queue is flushed
so no new work is added. However the check for adapter being removed is
racy in that the adapter can go into REMOVING state just after we check
and we might end up adding work just as it is being flushed (or after).
The ->rwi_lock is already being used to serialize queue/dequeue work.
Extend its usage ensure there is no race when scheduling/flushing work.

shift every existing flag down into a contiguous assignment.
PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S

flag instead of canibalizing one from phydev->dev_flags for that

Hardware comes up with default max frame size set to 1518. When using it
with switch it results in actual Ethernet MTU 1492:
1518 - 14 (Ethernet header) - 4 (Broadcom's tag) - 4 (802.1q) - 4 (FCS)
Above means hardware in its default state can't handle standard Ethernet
traffic (MTU 1500).
Define maximum possible Ethernet overhead and always set MAC max frame
length accordingly. This change fixes handling Ethernet frames of length
1506 - 1514.

test_global_func4 fails on s390 as reported by Yauheni in [1].
The immediate problem is that the zext code includes the instruction,
whose result needs to be zero-extended, into the zero-extension
patchlet, and if this instruction happens to be a branch, then its
delta is not adjusted. As a result, the verifier rejects the program
later.
However, according to [2], as far as the verifier's algorithm is
concerned and as specified by the insn_no_def() function, branching
insns do not define anything. This includes call insns, even though
one might argue that they define %r0.
This means that the real problem is that zero extension kicks in at
all. This happens because clear_caller_saved_regs() sets BPF_REG_0's
subreg_def after global function calls. This can be fixed in many
ways; this patch mimics what helper function call handling already
does.

default
The sja1105 driver has a limitation, extensively described under
Documentation/networking/dsa/sja1105.rst and
Documentation/networking/devlink/sja1105.rst, which says that when the
ports are under a bridge with vlan_filtering=1, traffic to and from
the network stack is not possible, unless the driver-specific
best_effort_vlan_filtering devlink parameter is enabled.
For users, this creates a 'wtf' moment. They need to go to the
documentation and find about the existence of this property, then maybe
install devlink and set it to true.
Having best_effort_vlan_filtering enabled by the kernel by default
delays that 'wtf' moment (maybe up to the point that it never even
happens). The user doesn't need to care that the driver supports
addressing the ports individually by retagging VLAN IDs until he/she
needs to use more than 32 VLAN IDs (since there can be at most 32
retagging rules). Only then do they need to think whether they need the
full VLAN table, at the expense of no individual port addressing, or
not.
But the odds that an sja1105 user will need more than 32 VLANs
terminated by the CPU is probably low. And, if we were to follow the
principle that more advanced use cases should require more advanced
preparation steps, then it makes more sense for ping to 'just work'
while CPU termination of > 32 VLAN IDs to require a bit more forethought
and possibly a driver-specific devlink param.
So we should be able to safely change the default here, and make this
driver act just a little bit more sanely out of the box.

The usage of in_interrupt() in non-core code is phased out. Ideally the
information of the calling context should be passed by the callers or the
functions be split as appropriate.
The attempt to consolidate the code by passing an arguemnt or by
distangling it failed due lack of knowledge about this driver and because
the call chains are hard to follow.
As a stop gap use netif_rx_any_context() which invokes the correct code path
depending on context and confines the in_interrupt() usage to core code.

My prior cleanup missed that tcp_data_ready() has to look at SOCK_DONE.
Otherwise, an application using SO_RCVLOWAT will not get EPOLLIN event
if a FIN is received in the middle of expected payload.
The reason SOCK_DONE is not examined in tcp_epollin_ready()
is that tcp_poll() catches the FIN because tcp_fin()
is also setting RCV_SHUTDOWN into sk->sk_shutdown

Smatch is confused by the fact that a 32-bit BIT(port) macro is passed
as argument to the ocelot_ifh_set_dest function and warns:
ocelot_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
seville_xmit() warn: should '(((1))) << (dp->index)' be a 64 bit type?
The destination port mask is copied into a 12-bit field of the packet,
starting at bit offset 67 and ending at 56.
So this DSA tagging protocol supports at most 12 bits, which is clearly
less than 32. Attempting to send to a port number > 12 will cause the
packing() call to truncate way before there will be 32-bit truncation
due to type promotion of the BIT(port) argument towards u64.
Therefore, smatch's fears that BIT(port) will do the wrong thing and
cause unexpected truncation for "port" values >= 32 are unfounded.
Nonetheless, let's silence the warning by explicitly passing an u64
value to ocelot_ifh_set_dest, such that the compiler does not need to do
a questionable type promotion.

The documentation for the PHY update [1] states:
Loop 4 times with index i
If PHY Revision >= 3
Copy table[i] to coef[i]
Otherwise
Set coef[i] to 0
the copy of the table to coef is currently implemented the wrong way
around, table is being updated from uninitialized values in coeff.
Fix this by swapping the assignment around.

The Max imm data size in cxgb4 is not similar to the max imm data size
in the chtls. This caused an mismatch in output of is_ofld_imm() of
cxgb4 and chtls. So fixed this by keeping the max wreq size of imm data
same in both chtls and cxgb4 as MAX_IMM_OFLD_TX_DATA_WR_LEN.
As cxgb4's max imm. data value for ofld packets is changed to
MAX_IMM_OFLD_TX_DATA_WR_LEN. Using the same in cxgbit also.

idt77252 is broken and wont load on amd64 systems
modprobe idt77252 shows the following
idt77252_init: skb->cb is too small (48 < 56)
Add packed attribute to struct idt77252_skb_prv and struct atm_skb_data
so that the total size can be <= sizeof(skb->cb)
Also convert runtime size check to buildtime size check in
idt77252_init()

A userspace daemon like firewalld might need to monitor for netlink
updates to detect its ruleset removal by the (global) flush ruleset
command to ensure ruleset persistency. This adds extra complexity from
userspace and, for some little time, the firewall policy is not in
place.
This patch adds the NFT_TABLE_F_OWNER flag which allows a userspace
program to own the table that creates in exclusivity.
Tables that are owned...
- can only be updated and removed by the owner, non-owners hit EPERM if
they try to update it or remove it.
- are destroyed when the owner closes the netlink socket or the process
is gone (implicit netlink socket closure).
- are skipped by the global flush ruleset command.
- are listed in the global ruleset.
The userspace process that sets on the NFT_TABLE_F_OWNER flag need to
leave open the netlink socket.
A new NFTA_TABLE_OWNER netlink attribute specifies the netlink port ID
to identify the owner from userspace.
This patch also updates error reporting when an unknown table flag is
specified to change it from EINVAL to EOPNOTSUPP given that EINVAL is
usually reserved to report for malformed netlink messages to userspace.
