The nvethernet driver fails to build for Linux v5.14 and Linux v5.17+
kernels. In Linux v5.15 the return type of the get/set_coalesce
callbacks were updated. In Linux v5.17 the parameters for the
get/set_ringparam callbacks were updated. In Linux v6.1 the
weight parameter for the netif_napi_add() function was removed and the
function netif_napi_add_weight() was added for passing the weight
parameter. Add the necessary kernel version checks to ensure that the
drivers build with the different versions of the Linux kernel.

Issue: If OSI_RX_SWCX_REUSE flag is set in OSI then
OSD will not reallocate the buffer for that descriptor
index. It will re-use the same buffer virt/physical
addresses. If that buffer is a reserved buffer then OSI
will not process that so it will result in packet drops.
Fix: Reuse the buffer is OSI_RX_SWCX_REUSE flag is set
and the buffer is not a reserved buffer.

Issue: In the current scenrio, when the remote
interface is brought down and up. There is no way
of getting the link up again with the remote device
which in turn fails the data transfers even though
interface from other end is brought up.
Fix: When interface is gone down on the other side,
MAC receives local faults and in this scenario
no data should be sent to MAC, so disable network
queues and initiate the lane bring up process for
monitoring the link status. Once the link is up,
re enable the network queues for data transfers.
Also added support for enabling driver logs using
msglvl of ethtool

Issue: If WOL is enabled after running "./ethtool -s eth0 wol g"
command there will not be any eapol frames transaction, hence macsec
will be disabled. As macsec is disabled before suspend we are not
enabling it back once resumed. Because of this eapol frames are also
sent with sec-tag as byp_lut is not programmed.
Fix: Instead of depending on the macsec state, check if there is any
supplicant running, if there is any supplicant then enable the macsec
post resume.

workqueue is not getting scheduled at the driver layer to consume
the Tx timestamp from the OSI layer which resulted in tx_timeout

Fix: Invoke the timestamp consume function in tx done instead
of scheduling through workqueue. Schedule the work queue only
if the timestamp is not found.

Issue:
OSD Driver maintains a local MC address list to avoid the programming
old addresses again into HW when new MC address list passed from the
network stack.
Its observed MC address index for a specific address is different once a
MC address deleted from the list. Because of this new MC address which
is passed in new list is overwriting the old MC address.
Fix:
Program the entire list every time when network stack passes it instead
of maintaining local list at driver.
