====================
do a single memdup_user in sctp_setsockopt v2

here is a resend of my series to lift the copy_from_user out of the
individual sctp sockopt handlers into the main sctp_setsockopt
routine.

Changes since v1:
 - fixes a few sizeof calls.
 - use memzero_explicit in sctp_setsockopt_auth_key instead of special
   casing it for a kzfree in the caller
 - remove some minor cleanups from sctp_setsockopt_autoclose to keep
   it closer to the existing version
 - add another little only vaguely related cleanup patch

https://lore.kernel.org/netdev/1567779344-30965-1-git-send-email-claudiu.manoil@nxp.com/
They have never been resent. I've picked them up, addressed Andrews
comments, fixed some more bugs and asked Claudiu if I can keep their SOB
tags; he agreed. I've tested this on our board which happens to have a
bootloader which doesn't do the enetc setup in all cases. Though, only
SGMII mode was tested.

changes since v6:
 - dropped _LPA_ infix for USXGMII constants

changes since v5:
 - fixed pcs->autoneg_complete and pcs->link assignment. Thanks Vladimir.

changes since v4:
 - moved (and renamed) the USXGMII constants to include/uapi/linux/mdio.h.
   Suggested by Russell King.

changes since v3:
 - rebased to latest net-next where devm_mdiobus_free() was removed.
   replace it by mdiobus_free(). The internal MDIO bus is optional, if
   there is any error, we try to run with the bootloader default PCS
   settings, thus in the error case, we need to free the mdiobus.

changes since v2:
 - removed SOBs from "net: enetc: Initialize SerDes for SGMII and USXGMII
   protocols" because almost everything has changed.
 - get a phy_device for the internal PCS PHY so we can use the phy_
   functions instead of raw mdiobus writes
 - reuse macros already defined in fsl_mdio.h, move missing bits from
   felix to fsl_mdio.h, because they share the same PCS PHY building
   block
 - added 2500BaseX mode (based on felix init routine)
 - changed xgmii mode to usxgmii mode, because it is actually USXGMII and
   felix does the same.
 - fixed devad, which is 0x1f (MMD_VEND2)

changes since v1:
 - mdiobus id is '"imdio-%s", dev_name(dev)' because the plain dev_name()
   is used by the emdio.
 - use mdiobus_write() instead of imdio->write(imdio, ..), since this is
   already a full featured mdiobus
 - set phy_mask to ~0 to avoid scanning the bus
 - use phy_interface_mode_is_rgmii(phy_mode) to also include the RGMII
   modes with pad delays.
 - move enetc_imdio_init() to enetc_pf.c, there shouldn't be any other
   users, should it?
 - renamed serdes to SerDes
 - printing the error code of mdiobus_register() in the error path
 - call mdiobus_unregister() on _remove()
 - call devm_mdiobus_free() if mdiobus_register() fails, since an
