Since d49e83eac3, iflib(9) is ready
for this change.
While at it, make isc_driver_version strings (static) const where
not apparently un-const on purpose, too.
This reduces the size of the amd64 GENERIC by about 10 KiB.
Summary:
Hardware supports up to 128 entries of multicast filters. If there is more,
filters should be removed and multicast promiscuous enabled. In case
user deletes the multicast address and overall count is less than 128,
multicast promiscuous mode should be disabled and all the filters
reapplied into the HW.
Currently driver only enables multicast promiscuous mode and deletes
the entries without any information to the user and it's not capable of
reapplying the filters once count is less than 128.
Address that by:
1. Add logging
2. Add logic in case multicast promiscuous is enabled and user lowers
the number of multicast entries to <128.
3. Fix a bug where driver removes different MAC entries along with the one
that's being deleted by the user.

Doing a 'dd' over iscsi will reliably cause stalls. Tx
cleaning _should_ reliably happen as data is sent.
However, currently if the transmit queue fills it will
wait until the iflib timer (hz/2) runs.
This change causes the the tx taskq thread to be run
if there are completed descriptors.
While here:
- make timer interrupt delay a sysctl
- simplify txd_db_check handling
- comment on INTR types
Background on the change:
Initially doorbell updates were minimized by only writing to the register
on every fourth packet. If txq_drain would return without writing to the
doorbell it scheduled a callout on the next tick to do the doorbell write
to ensure that the write otherwise happened "soon". At that time a sysctl
was added for users to avoid the potential added latency by simply writing
to the doorbell register on every packet. This worked perfectly well for
e1000 and ixgbe ... and appeared to work well on ixl. However, as it
turned out there was a race to this approach that would lockup the ixl MAC.
It was possible for a lower producer index to be written after a higher one.
On e1000 and ixgbe this was harmless - on ixl it was fatal. My initial
response was to add a lock around doorbell writes - fixing the problem but
adding an unacceptable amount of lock contention.
The next iteration was to use transmit interrupts to drive delayed doorbell
writes. If there were no packets in the queue all doorbell writes would be
immediate as the queue started to fill up we could delay doorbell writes
further and further. At the start of drain if we've cleaned any packets we
know we've moved the state machine along and we write the doorbell (an
obvious missing optimization was to skip that doorbell write if db_pending
is zero). This change required that tx interrupts be scheduled periodically
as opposed to just when the hardware txq was full. However, that just leads
to our next problem.
Initially dedicated msix vectors were used for both tx and rx. However, it
was often possible to use up all available vectors before we set up all the
queues we wanted. By having rx and tx share a vector for a given queue we
could halve the number of vectors used by a given configuration. The problem
here is that with this change only e1000 passed the necessary value to have
the fast interrupt drive tx when appropriate.

Pursuant to r360398, implement driver-specific versions of the

Some (if not most?) Intel network cards don't need reinitializing when a
VLAN is added or removed from the device hardware, so these implement
ifdi_needs_restart in a way that tell iflib not to bring the interface
up or down when a VLAN is added or removed, regardless of whether the
VLAN_HWFILTER interface capability flag is set or not.
This could potentially solve several PRs relating to link flaps that

From Jake:
iflib_fl_setup calculates a suitable buffer size for the Rx mbufs based
on the isc_max_frame_size value that drivers setup. This calculation is
repeated by drivers when programming their hardware with the size of
each Rx buffer.
This can lead to a mismatch where the iflib mbuf size is different from
the expected size of the buffer as programmed by the hardware. This can
lead to unexpected results.
If iflib ever wants to support mbuf sizes larger than one page, every
driver must be updated to account for the new possible buffer sizes.
Fix this by calculating the mbuf size prior to calling IFDI_INIT, and
adding the iflib_get_rx_mbuf_sz function which will expose this value to
drivers, so that they do not repeat the same calculation.
