This commit removed calls to rtl_set_rx_mode(). This is ok for the
standard path if the link is brought up, however it breaks system
resume from suspend. Link comes up but no network traffic.
Meanwhile common code from rtl_hw_start_8169/8101/8168() was moved
to rtl_hw_start(), therefore re-add the call to rtl_set_rx_mode()
there.
Due to adding this call we have to move definition of rtl_hw_start()
after definition of rtl_set_rx_mode().

The bpf syscall and selftests conflicts were trivial
overlapping changes.
The r8169 change involved moving the added mdelay from 'net' into a
different function.
A TLS close bug fix overlapped with the splitting of the TLS state
into separate TX and RX parts. I just expanded the tests in the bug
fix from "ctx->conf == X" into "ctx->tx_conf == X && ctx->rx_conf
== X".

Since commit a92a08499b "r8169: improve runtime pm in general and
suspend unused ports" interfaces w/o link are runtime-suspended after
10s. On systems where drivers take longer to load this can lead to the
situation that the interface is runtime-suspended already when it's
initially brought up.
This shouldn't be a problem because rtl_open() resumes MAC/PHY.
However with at least one chip version the interface doesn't properly
come up, as reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=199549
The vendor driver uses a delay to give certain chip versions some
time to resume before starting the PHY configuration. So let's do
the same. I don't know which chip versions may be affected,
therefore apply this delay always.
This patch was reported to fix the issue for RTL8168h.
I was able to reproduce the issue on an Asus H310I-Plus which also
uses a RTL8168h. Also in my case the patch fixed the issue.

Some chips have a non-zero function id, however instead of hardcoding
the id's (CSIAR_FUNC_NIC and CSIAR_FUNC_NIC2) we can get them
dynamically via PCI_FUNC(pci_dev->devfn). This way we can get rid
of the csi_ops.
In general csi is just a fallback mechanism for PCI config space
access in case no native access is supported. Therefore let's
try native access first.
I checked with Realtek regarding the functionality of config space
byte 0x070f and according to them it controls the L0s/L1
entrance latency.
Currently ASPM is disabled in general and therefore this value
isn't used. However we may introduce a whitelist for chips
where ASPM is known to work, therefore let's keep this code.

Currently done:
- if mac_version in (01, 02, 03, 04)
RTL_W8(tp, ChipCmd, CmdTxEnb | CmdRxEnb);
- if mac_version in (01, 02, 03, 04)
rtl_set_rx_tx_config_registers(tp);
- if mac_version not in (01, 02, 03, 04)
RTL_W8(tp, ChipCmd, CmdTxEnb | CmdRxEnb);
rtl_set_rx_tx_config_registers(tp);
So we do exactly the same independent of chip version and can simplify
the code.

tp->cp_cmd is supposed to reflect the current value of the CplusCmd
register. Several (quite old) changes however directly change this
register w/o updating tp->cp_cmd. Also we have places in the code
reading this register where we could use the cached value.
In addition:
- Properly initialize tp->cmd with the register value.
- In rtl_hw_start_8169 remove one setting of PCIMulRW because it's
set unconditionally anyway a few lines later.
- In rtl_hw_start_8168 properly mask out the INTT bits before
setting INTT_1. So far we rely on both bits being zero.

pci_set_drvdata() is called only after registering the net_device,
therefore we could run into a NPE if one of the functions using
driver_data is called before it's set.
Fix this by calling pci_set_drvdata() before registering the

This fix is a candidate for stable. As far as I can see the
bug has been there in kernel version 3.2 already, therefore
I can't provide a reference which commit is fixed by it.
The fix may need small adjustments per kernel version because
due to other changes the label which is jumped to if
