An older GCC compiler complains:

kernel/bpf/verifier.c: In function 'bpf_check':
kernel/bpf/verifier.c:4***:13: error: 'prev_offset' may be used uninitialized
      in this function [-Werror=maybe-uninitialized]
   } else if (krecord[i].insn_offset <= prev_offset) {

kernel/bpf/verifier.c:4***:38: note: 'prev_offset' was declared here
  u32 i, nfuncs, urec_size, min_size, prev_offset;

Although the compiler is wrong here, the patch makes sure
that prev_offset is always initialized, just to silence the warning.

====================
Previous maximum supported integer bit width is 64. But
the __int128 type has been supported by most (if not all)
64bit architectures including bpf for both gcc and clang.

The kernel itself uses __int128 for x64 and arm64. Some bcc
tools are using __int128 in bpf programs to describe ipv6
addresses. Without 128bit int support, the vmlinux BTF won't
work and those bpf programs using __int128 cannot utilize BTF.

This patch set therefore implements BTF __int128 support.

Currently, btf only supports up to 64-bit integer.
On the other hand, 128bit support for gcc and clang
has existed for a long time. For example, both gcc 4.8
and llvm 3.7 supports types "__int128" and
"unsigned __int128" for virtually all 64bit architectures
including bpf.

The requirement for __int128 support comes from two areas:
  . bpf program may use __int128. For example, some bcc tools
    (https://github.com/iovisor/bcc/tree/master/tools),
    mostly tcp v6 related, tcpstates.py, tcpaccept.py, etc.,
    are using __int128 to represent the ipv6 addresses.
  . linux itself is using __int128 types. Hence supporting
    __int128 type in BTF is required for vmlinux BTF,
    which will be used by "compile once and run everywhere"
    and other projects.

For 128bit integer, instead of base-10, hex numbers are pretty
printed out as large decimal number is hard to decipher, e.g.,
for ipv6 addresses.

100GbE Intel Wired LAN Driver Updates 2019-01-15

This series contains updates to the ice driver only.

Bruce fixes an unused variable build warning, which was introduced with
the commit 2fd527b7 ("net: ndo_bridge_setlink: Add extack").  Added
ethtool support for get_eeprom and get_eeprom_len operations.  Added
support for bringing down the PHY link optional when the interface is
administratively downed.

Anirudh refactors the transmit scheduler functions, which results in
reduced code duplication and adds a helper function, which all the
scheduler functions call instead.  Added an LED blinking handler to
ethtool.  Reworked the queue management code to allow for reuse in
future XDP feature support.  Updates the driver to be able to preserve
the aggregator list after reset by moving it out of port_info and into
ice_hw.  Added the ability to offload SCTP checksum calculation to the
hardware.  Added support for new PHY types, which support higher link
speeds.

Md Fahad makes sure that RSS lookup table and hash key get configured
during the rebuild path after a reset.

Brett updates the driver to set the physical link state according to the
netdev state (up/down).  Added support for adaptive/dynamic interrupt
moderation in the ice driver, along with the ethtool operations needed.

Tony adds software timestamping support by using
ethtool_op_get_ts_info().

Currently the driver does not support adaptive/dynamic interrupt
moderation. This patch adds support for this. Also, adaptive/dynamic
interrupt moderation is turned on by default upon driver load.

In order to support adaptive interrupt moderation, two functions were
added, ice_update_itr() and ice_itr_divisor(). These are used to
determine the current packet load and to determine a divisor based
on link speed respectively.

This patch also adds the ICE_ITR_GRAN_S define that is used in the
hot-path when setting a new ITR value. The shift is used to pet two
birds with one hand, set the ITR value while re-enabling the
interrupt. Also, the ICE_ITR_GRAN_S is defined as 1 because the device
has a ITR granularity of 2usecs.

existing pf->flags bitmap to store them, and add the link-down-on-close
ethtool private flag to optionally bring down the PHY link when the
interface is administratively downed.

When a netdev is set up/down we need to set the phsyical link state
accordingly. This patch adds that functionality by calling
ice_force_phys_link_state(vsi, link_up) in both the ice_stop() and
ice_open() paths.

In order to force link, ice_force_phys_link_state(vsi, link_up) will
first determine the current phy capabilities. If link has not changed
there is nothing to do. If link has changed, previous PHY capabilities
are saved and the "Enable Automatic Link Update" and "Link Establishment
State Machine (LESM)" enable bits are set. Then the new PHY config is
saved. The "Enable Automatic Link Update" will force the FW to execute
Setup link and restart auto-negotiation. This *should* then result in a
"Link Status Event (LSE)" which will cause the driver to get the current
link status.

Add support for get_eeprom and get_eeprom_len ethtool ops

Specification states that PF software accesses NVM (shadow-ram) via AQ
commands (e.g. NVM Read, NVM Write) in the range 0x000000-0x00FFFF (64KB),
so the get_eeprom_len op should return 64KB.  If additional regions of the
16MB NVM must be read, another access method must be used.

The ethtool kernel code, by default, will ask for multiple page-size hunks
of the NVM not to exceed the value returned by ice_get_eeprom_len().
ice_read_sr_buf() deals with arch page sizes different than 4KB.

Commit 2fd527b7 ("net: ndo_bridge_setlink: Add extack") added a new
parameter "extack" to ice_bridge_setlink but this parameter isn't used
by the function. This results in a warning: unused parameter ‘extack’
[-Wunused-parameter]. Fix that by adding an "__always_unused" qualifier.
