macsec: Enable devices to advertise whether they update sk_buff md_dst during offloads

macsec: Enable devices to advertise whether they update sk_buff md_dst during offloads
commit 475747a19316b08e856c666a20503e73d7ed67ed upstream.
Omit rx_use_md_dst comment in upstream commit since macsec_ops is not
documented.
Cannot know whether a Rx skb missing md_dst is intended for MACsec or not
without knowing whether the device is able to update this field during an
offload. Assume that an offload to a MACsec device cannot support updating
md_dst by default. Capable devices can advertise that they do indicate that
an skb is related to a MACsec offloaded packet using the md_dst.

net: macsec: indicate next pn update when offloading
Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.
The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case
Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case
Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \
ead3664f508eb06c40ac7104cdae4ce5
$ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case

macsec: add functions to get macsec real netdevice and check offload
Given a macsec net_device add two functions to return the real net_device
for that device, and check if that macsec device is offloaded or not.
This is needed for auxiliary drivers that implement MACsec offload, but
have flows which are triggered over the macsec net_device, this allows
the drivers in such cases to verify if the device is offloaded or not,
and to access the real device of that macsec device, which would
belong to the driver, and would be needed for the offload procedure.

macsec: Use helper macsec_netdev_priv for offload drivers
Now macsec on top of vlan can be offloaded to macsec offloading
devices so that VLAN tag is sent in clear text on wire i.e,
packet structure is DMAC|SMAC|VLAN|SECTAG. Offloading devices can
simply enable NETIF_F_HW_MACSEC feature in netdev->vlan_features for
this to work. But the logic in offloading drivers to retrieve the
private structure from netdev needs to be changed to check whether
the netdev received is real device or a vlan device and get private
structure accordingly. This patch changes the offloading drivers to
use helper macsec_netdev_priv instead of netdev_priv.

macsec: Support XPN frame handling - IEEE 802.1AEbw
Support extended packet number cipher suites (802.1AEbw) frames handling.
This does not include the needed netlink patches.
* Added xpn boolean field to `struct macsec_secy`.
* Added ssci field to `struct_macsec_tx_sa` (802.1AE figure 10-5).
* Added ssci field to `struct_macsec_rx_sa` (802.1AE figure 10-5).
* Added salt field to `struct macsec_key` (802.1AE 10.7 NOTE 1).
* Created pn_t type for easy access to lower and upper halves.
* Created salt_t type for easy access to the "ssci" and "pn" parts.
* Created `macsec_fill_iv_xpn` function to create IV in XPN mode.
* Support in PN recovery and preliminary replay check in XPN mode.
In addition, according to IEEE 802.1AEbw figure 10-5, the PN of incoming
frame can be 0 when XPN cipher suite is used, so fixed the function
`macsec_validate_skb` to fail on PN=0 only if XPN is off.

net: macsec: introduce the macsec_context structure
This patch introduces the macsec_context structure. It will be used
in the kernel to exchange information between the common MACsec
implementation (macsec.c) and the MACsec hardware offloading
implementations. This structure contains pointers to MACsec specific
structures which contain the actual MACsec configuration, and to the
underlying device (phydev for now).

net: macsec: move some definitions in a dedicated header
This patch moves some structure, type and identifier definitions into a
MACsec specific header. This patch does not modify how the MACsec code
is running and only move things around. This is a preparation for the
future MACsec hardware offloading support, which will re-use those
definitions outside macsec.c.

net: macsec: fix the length used to copy the key for offloading
[ Upstream commit 1f7fe5121127e037b86592ba42ce36515ea0e3f7 ]
The key length used when offloading macsec to Ethernet or PHY drivers
was set to MACSEC_KEYID_LEN (16), which is an issue as:
- This was never meant to be the key length.
- The key length can be > 16.
Fix this by using MACSEC_MAX_KEY_LEN to store the key (the max length
accepted in uAPI) and secy->key_len to copy it.

macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)
Netlink support of extended packet number cipher suites,
allows adding and updating XPN macsec interfaces.
Added support in:
* Creating interfaces with GCM-AES-XPN-128 and GCM-AES-XPN-256 suites.
* Setting and getting 64bit packet numbers with of SAs.
* Setting (only on SA creation) and getting ssci of SAs.
* Setting salt when installing a SAK.
Added 2 cipher suite identifiers according to 802.1AE-2018 table 14-1:
* MACSEC_CIPHER_ID_GCM_AES_XPN_128
* MACSEC_CIPHER_ID_GCM_AES_XPN_256
In addition, added 2 new netlink attribute types:
* MACSEC_SA_ATTR_SSCI
* MACSEC_SA_ATTR_SALT
Depends on: macsec: Support XPN frame handling - IEEE 802.1AEbw.
