A few PHY drivers have the GPLv2 license text. They then either have

Since the license text is much easier to understand than either the

licence, and fixup with others when there are contradictions.

8 years ago, as part of 6f0333b8fde4 ("r8169: use 50% less ram for RX
ring"), the alignment requirement for rx buffers was silently changed
from 8 bytes to 16 bytes. I found nothing explaining this, also the
chip specs I have only mention an 8 byte requirement.
AFAICS kmalloc_node() guarantees allocated memory to be at least
"long long" aligned, what is 8 bytes on a 32 bit machine.
So we can take this memory as-is and avoid some overhead by changing
the alignment requirement back to 8 bytes.

This patch adds support for extended statistics (xstats) call to the
bonding. The first user would be the 3ad code which counts the following
events:
- LACPDU Rx/Tx
- LACPDU unknown type Rx
- LACPDU illegal Rx
- Marker Rx/Tx
- Marker response Rx/Tx
- Marker unknown type Rx
All of these are exported via netlink as separate attributes to be
easily extensible as we plan to add more in the future.
Similar to how the bridge and other xstats exports, the structure
inside is:
[ IFLA_STATS_LINK_XSTATS ]
-> [ LINK_XSTATS_TYPE_BOND ]
-> [ BOND_XSTATS_3AD ]
-> [ 3ad stats attributes ]
With this structure it's easy to add more stat types later.

Commit cbffaf7aa09e ("can: flexcan: Always use last mailbox for TX")
introduced a loop letting i run up to (including) ARRAY_SIZE(regs->mb)
and in the body accessed regs->mb[i] which is an out-of-bounds array
access that then resulted in an access to an reserved register area.
Later this was changed by commit 0517961ccdf1 ("can: flexcan: Add
provision for variable payload size") to iterate a bit differently but
still runs one iteration too much resulting to call
flexcan_get_mb(priv, priv->mb_count)
which results in a WARN_ON and then a NULL pointer exception. This
only affects devices compatible with "fsl,p1010-flexcan",
"fsl,imx53-flexcan", "fsl,imx35-flexcan", "fsl,imx25-flexcan",
"fsl,imx28-flexcan", so newer i.MX SoCs are not affected.

This patch revert commit 7da11ba5c506
("can: dev: __can_get_echo_skb(): print error message, if trying to echo non existing skb")
After introduction of this change we encountered following new error
message on various i.MX plattforms (flexcan):
| flexcan 53fc8000.can can0: __can_get_echo_skb: BUG! Trying to echo non
| existing skb: can_priv::echo_skb[0]
The introduction of the message was a mistake because
priv->echo_skb[idx] = NULL is a perfectly valid in following case: If
CAN_RAW_LOOPBACK is disabled (setsockopt) in applications, the pkt_type
of the tx skb's given to can_put_echo_skb is set to PACKET_LOOPBACK. In
this case can_put_echo_skb will not set priv->echo_skb[idx]. It is
therefore kept NULL.
As additional argument for revert: The order of check and usage of idx
was changed. idx is used to access an array element before checking it's
boundaries.
