ix.4: Sort chip names.

ix: Sync with Intel's ix-3.2.17.

- Add several new chips.
- Add software workaround for 82598 errata #26.

polling: Implement direct input support.

When "direct input" is enabled by driver, driver's RX polling handler
will run ethernet/ip/tcp processing directly, which avoids cache-miss

polling: Implement direct input support.

When "direct input" is enabled by driver, driver's RX polling handler
will run ethernet/ip/tcp processing directly, which avoids cache-miss
on mbufs themselves. Currently it is enabled on ix(4) by default.

The normal IP forwarding performance is improved by %12, while the fast
IP forwarding performance is improved by 10%. 13.2Mpps is achieved for
dual side IP forwarding!

1 request/connection HTTP/1.1 performance and avg-latency stay same,
but the latency is further stablized:
1K 5.20ms -> 4.60ms
8K 6.43ms -> 5.76ms
16K 16.30ms -> 14.90ms

ix: Disable flow control by default.

ix: Use ringmap to do MSI-X cpu assignment and fill redirect table.

ix: Update to Intel ix-2.8.2

This update adds more chips support.

properly at least on my 82599 w/ DAC; though "autoselect" is still
the recommended mode.

ix: Integrate ifmedia flow control support.

Other minor bits:
- Set media to IFM_NONE, if there is no link yet.
- Remove no longer used dev.ix.Y.flow_ctrl sysctl node.
ifconfig ixY [mediaopt|-medi

- Remove no longer used dev.ix.Y.flow_ctrl sysctl node.
ifconfig ixY [mediaopt|-mediaopt] [rxpause|txpause|forcepause]
should be used instead.

ix.4: ixX -> ixY and dev.ix.X -> dev.ix.Y

kernel: Use the new auto-created sysctl ctx/tree in various drivers.

Everywhere where we formerly rolled a hw.fooX.* per-device ctx/tree
ourselves.

This commit switches it to dev.foo.X.*

ix.4: Fix description of TSO and multiple tranmission queue arbitration.

ix.4: Update according to the overhaul of ix(4)

ix.4: Mention polling(4) support.

ix: Import Intel ixgbe-2.5.15

MSI and legacy interrupt (line based interrupt) are working as of this
commit. polling(4) will be supported and MSI-X will be brought back in
the later commits.

ixgbe

ix: Import Intel ixgbe-2.5.15

MSI and legacy interrupt (line based interrupt) are working as of this
commit. polling(4) will be supported and MSI-X will be brought back in
the later commits.

ixgbe is renamed to ix, which is consistent w/ the interface name, and
this makes 'ifconfig ix0' work as expected.

Local changes:
- Reorganize RX and TX ring data structure; nuke useless 'queue'.
- Rework RX and TX ring creation, destroy, initialization and cleanup.
- Reorganize interrupt related data structure. This also prepares for
bringing MSI-X back.
- Rework interrupt allocation.
- Rework MSI and legacy interrupt handler.
- Enable RSS (2 RX rings) even if MSI or legacy interrupt is used.
- Apply DragonFly specific RSS configuration.
- Partially rework RX code path.
- Enable TX header write-back.
- Rework TX code path and TX watchdog mechanism.
- Rework busdma(9) related bits.
- Rework ifnet.if_ioctl method.
- Reorganize initialize and stop code.
- Reorganize attach and detach code.
- Code clean up.
