Replace magic numbers with proper constants. The original patch is
from Andrew, I extended / adjusted certain parts:
- Use decimal bit numbers. The datasheet uses hex bit numbers 0 .. F.
- Order defines from highest to lowest bit numbers
- correct some typos
- add constant MDIO_AN_TX_VEND_INT_MASK2_LINK
- Remove few functional improvements from the patch, they will come as
a separate patch.

Shared buffer allocation is usually done in cell increments.
Drivers will either round up the allocation or refuse the
configuration if it's not an exact multiple of cell size.
Drivers know exactly the cell size of shared buffer, so help
out users by providing this information in dumps.

As part of y2038 solution, all internal uses of
struct timeval are replaced by struct __kernel_old_timeval
and struct compat_timeval by struct old_timeval32.
Make socket timestamps use these new types.
This is mainly to be able to verify that the kernel build
is y2038 safe when such non y2038 safe types are not
supported anymore.

{t4/t4_vf}_change_mac() API's were only doing additions to MPS_TCAM.
This will fail, when the number of tcam entries is limited particularly
in vf's.
This fix programs hash region with the mac address, when TCAM
addtion fails for {t4/t4vf}_change_mac(). Since the locally maintained
driver list for hash entries is shared across mac_{sync/unsync}(),
added an extra parameter if_mac to track the address added thorugh
{t4/t4vf}_change_mac()

The integrated PHY's of later RTL8168 network chips report the generic
PHYID 0x001cc800 (Realtek OUI, model and revision number both set to
zero) and therefore currently the genphy driver is used.
To be able to use the paged version of e.g. phy_write() we need a
PHY driver with the read_page and write_page callbacks implemented.
So basically make a copy of the genphy driver, just with the
read_page and write_page callbacks being set.

The following ALU32 logic shift supports are missing:
BPF_ALU | BPF_LSH | BPF_X
BPF_ALU | BPF_RSH | BPF_X
BPF_ALU | BPF_RSH | BPF_K
For BPF_RSH | BPF_K, it could be implemented using NFP direct shift
instruction. For the other BPF_X shifts, NFP indirect shifts sequences need
to be used.
Separate code-gen hook is assigned to each instruction to make the
implementation clear.

Shifts by zero do nothing, and should be treated as nops.
Even though compiler is not supposed to generate such instructions and
manual written assembly is unlikely to have them, but they are legal
instructions and have defined behavior.
This patch correct existing shifts code-gen to make sure they do nothing
when shift amount is zero except when the instruction is ALU32 for which
high bits need to be cleared.
For shift amount bigger than type size, already, NFP JIT back-end errors
out for immediate shift and only low 5 bits will be taken into account for
indirect shift which is the same as x86.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
instance = kzalloc(sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);

WoL handling for the RTL8168 family is a little bit tricky because of
different types of broken BIOS and/or chip quirks.
Two known issues:
1. Network properly resumes from suspend only if WoL is enabled in the chip.
2. Some notebooks wake up immediately if system is suspended and network
device is wakeup-enabled.
Few patches tried to deal with this:
7edf6d314cd0 ("r8169: disable WOL per default")
18041b523692 ("r8169: restore previous behavior to accept BIOS WoL
settings")
Currently we have the situation that the chip WoL settings as set by
the BIOS are respected (to prevent issue 1), but the device doesn't get
wakeup-enabled (to prevent issue 2).
This leads to another issue:
If systemd is told to set WoL it first checks whether the requested
settings are active already (and does nothing if yes). Due to the chip
WoL flags being set properly systemd assumes that WoL is configured
properly in our case. Result is that device doesn't get wakeup-enabled
and WoL doesn't work (until it's set e.g. by ethtool).
This patch now:
- leaves the chip WoL settings as is (to prevent issue 1)
- keeps the behavior to not wakeup-enable the device initially
(to prevent issue 2)
- In addition we report WoL as being disabled in get_wol, matching
that device isn't wakeup-enabled. If systemd is told to enable WoL,
it will therefore detect that it has to do something and will
call set_wol.
Of course the user still has the option to override this with
e.g. ethtool.
v2:
- Don't just exclude __rtl8169_get_wol() from compiling, remove it.
v3:
- adjust commit message

When the VF shares the same TC config as PF, the business
running on PF and VF must have samiliar module.
For simplicity, we are not considering VF sharing the same tc
configuration as PF use case, so this patch removes the support
of TC configuration from VF and forcing VF to just use single
TC.
