Marius Strobl 7f87c0406d Assorted TSO fixes for em(4)/iflib(9) and dead code removal: 
- Ever since the workaround for the silicon bug of TSO4 causing MAC hangs
  was committed in r295133, CSUM_TSO always got disabled unconditionally
  by em(4) on the first invocation of em_init_locked(). However, even with
  that problem fixed, it turned out that for at least e. g. 82579 not all
  necessary TSO workarounds are in place, still causing MAC hangs even at
  Gigabit speed. Thus, for stable/11, TSO usage was deliberately disabled
  in r323292 (r323293 for stable/10) for the EM-class by default, allowing
  users to turn it on if it happens to work with their particular EM MAC
  in a Gigabit-only environment.
  In head, the TSO workaround for speeds other than Gigabit was lost with
  the conversion to iflib(9) in r311849 (possibly along with another one
  or two TSO workarounds). Yet at the same time, for EM-class MACs TSO4
  got enabled by default again, causing device hangs. Therefore, change the
  default for this hardware class back to have TSO4 off, allowing users
  to turn it on manually if it happens to work in their environment as
  we do in stable/{10,11}. An alternative would be to add a whitelist of
  EM-class devices where TSO4 actually is reliable with the workarounds in
  place, but given that the advantage of TSO at Gigabit speed is rather
  limited - especially with the overhead of these workarounds -, that's
  really not worth it. [1]
  This change includes the addition of an isc_capabilities to struct
  if_softc_ctx so iflib(9) can also handle interface capabilities that
  shouldn't be enabled by default which is used to handle the default-off
  capabilities of e1000 as suggested by shurd@ and moving their handling
  from em_setup_interface() to em_if_attach_pre() accordingly.
- Although 82543 support TSO4 in theory, the former lem(4) didn't have
  support for TSO4, presumably because TSO4 is even more broken in the
  LEM-class of MACs than the later EM ones. Still, TSO4 for LEM-class
  devices was enabled as part of the conversion to iflib(9) in r311849,
  causing device hangs. So revert back to the pre-r311849 behavior of
  not supporting TSO4 for LEM-class at all, which includes not creating
  a TSO DMA tag in iflib(9) for devices not having IFCAP_TSO4 set. [2]
- In fact, the FreeBSD TCP stack can handle a TSO size of IP_MAXPACKET
  (65535) rather than FREEBSD_TSO_SIZE_MAX (65518). However, the TSO
  DMA must have a maxsize of the maximum TSO size plus the size of a
  VLAN header for software VLAN tagging. The iflib(9) converted em(4),
  thus, first correctly sets scctx->isc_tx_tso_size_max to EM_TSO_SIZE
  in em_if_attach_pre(), but later on overrides it with IP_MAXPACKET
  in em_setup_interface() (apparently, left-over from pre-iflib(9)
  times). So remove the later and correct iflib(9) to correctly cap
  the maximum TSO size reported to the stack at IP_MAXPACKET. While at
  it, let iflib(9) use if_sethwtsomax*().
  This change includes the addition of isc_tso_max{seg,}size DMA engine
  constraints for the TSO DMA tag to struct if_shared_ctx and letting
  iflib_txsd_alloc() automatically adjust the maxsize of that tag in case
  IFCAP_VLAN_MTU is supported as requested by shurd@.
- Move the if_setifheaderlen(9) call for adjusting the maximum Ethernet
  header length from {ixgbe,ixl,ixlv,ixv,em}_setup_interface() to iflib(9)
  so adjustment is automatically done in case IFCAP_VLAN_MTU is supported.
  As a consequence, this adjustment now is also done in case of bnxt(4)
  which missed it previously.
- Move the reduction of the maximum TSO segment count reported to the
  stack by the number of m_pullup(9) calls (which in the worst case,
  can add another mbuf and, thus, the requirement for another DMA
  segment each) in the transmit path for performance reasons from
  em_setup_interface() to iflib_txsd_alloc() as these pull-ups are now
  done in iflib_parse_header() rather than in the no longer existing
  em_xmit(). Moreover, this optimization applies to all drivers using
  iflib(9) and not just em(4); all in-tree iflib(9) consumers still
  have enough room to handle full size TSO packets. Also, reduce the
  adjustment to the maximum number of m_pullup(9)'s now performed in
  iflib_parse_header().
- Prior to the conversion of em(4)/igb(4)/lem(4) and ixl(4) to iflib(9)
  in r311849 and r335338 respectively, these drivers didn't enable
  IFCAP_VLAN_HWFILTER by default due to VLAN events not being passed
  through by lagg(4). With iflib(9), IFCAP_VLAN_HWFILTER was turned on
  by default but also lagg(4) was fixed in that regard in r203548. So
  just remove the now redundant and defunct IFCAP_VLAN_HWFILTER handling
  in {em,ixl,ixlv}_setup_interface().
- Nuke other redundant IFCAP_* setting in {em,ixl,ixlv}_setup_interface()
  which is (more completely) already done in {em,ixl,ixlv}_if_attach_pre()
  now.
- Remove some redundant/dead setting of scctx->isc_tx_csum_flags in
  em_if_attach_pre().
- Remove some IFCAP_* duplicated either directly or indirectly (e. g.
  via IFCAP_HWCSUM) in {EM,IGB,IXL}_CAPS.
- Don't bother to fiddle with IFCAP_HWSTATS in ixgbe(4)/ixgbev(4) as
  iflib(9) adds that capability unconditionally.
- Remove some unused macros from em(4).
- Bump __FreeBSD_version as some of the above changes require the modules
  of drivers using iflib(9) to be recompiled.
