net: phy: marvell10g updates

Here are some updates for marvell10g PHY driver.

I am still working on some more changes for this driver, but I would
like to have at least something reviewed / applied.

Changes since v3:
- added Andrew's Reviewed-by tags
- removed patches adding variadic-macro library and bitmap
  initialization macro - it causes warning that we are not currently
  able to fix easily. Instead the supported_interfaces bitmap is now
  initialized via a chip specific method
- added explanation of mactype initialization to commit message of patch
  07/16
- fixed repeated word in commit message of second to last patch

Changes since v2:
- code refactored to use an additional structure mv3310_chip describing
  mv3310 specific properties / operations for PHYs supported by this
  driver
- added separate phy_driver structures for 88X3340 and 88E2111
- removed 88E2180 specific code (dual-port and quad-port SXGMII modes
  are ignored for now)

Changes since v1:
- added various MACTYPEs support also for 88E21XX
- differentiate between specific models with same PHY_ID
- better check for compatible interface
- print exact model

Add support for all rate matching modes for 88X3310 (currently only

Add support for rate matching for 88E2110 (on 88E2110 the MACTYPE
register is at a different place).

Currently rate matching mode is selected by strapping pins (by setting
the MACTYPE register). There is work in progress to enable this driver
to deduce the best MACTYPE from the knowledge of which interface modes
are supported by the host, but this work is not finished yet.

The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port
(a u16) left 24 places. There are two subtle issues here, first the
shift gets promoted to an signed int and then sign extended to a u64.
If oct->pcie_port is 0x80 or more then the upper bits get sign extended
to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it
needs to be cast to a u64 for all the bits to not overflow.

It is entirely possible that the u16 port value is never large enough
for this to fail, but it is useful to fix unintended overflows such
as this.

Fix this by casting the port parameter to the macro to a u64 before
the shift.

====================
pull-request: can-next 2021-04-07

this is a pull request of 6 patches for net-next/master.

The first patch targets the CAN driver infrastructure, it improves the
alloc_can{,fd}_skb() function to set the pointer to the CAN frame to
NULL if skb allocation fails.

The next patch adds missing error handling to the m_can driver's RX
path (the code was introduced in -next, no need to backport).

In the next patch an unused constant is removed from an enum in the
c_can driver.

The last 3 patches target the mcp251xfd driver. They add BQL support
and try to work around a sometimes broken CRC when reading the TBC
register.

Here is only one place where we want to specify new_ifindex. In all
other cases, callers pass 0 as new_ifindex. It looks reasonable to add a
low-level function with new_ifindex and to convert
