This patch seeks to clean up the timer related code. It begins by
moving one-time timer setup code from tg3_open() to tg3_init_one().
It then creates a function that encapsulates the code needed to start

this patch moves all the timer functions to a more suitable location.

If an error happens in the tx completion thread, tg3_reset_task will be
scheduled and TX_RECOVERY_PENDING will be set. The TX_RECOVERY_PENDING
flag causes tg3_poll[_msix] to return early before doing much of its
work. Tg3_reset_task() gets canceled when the configuration of the
device is changing, which always results in a chip reset. When this
happens, the TX_RECOVERY_PENDING flag may be left set, which would
unnecessarily hinder tg3_poll from doing work. This patch fixes the
problem.

tg3_phy_copper_begin() has code that configures the link
advertisements through the use of the link_config.speed and
link_config.duplex members. The driver does not internally use these
members in this way, nor is it (currently) permitted via the ethtool
interface. This patch removes the dead code.

The tg3 driver tried to detect link changes by comparing the tg3 local
active_speed member with SPEED_UNKNOWN (or formerly SPEED_INVALID).
This check is not correct, since phylib will never set its speed member
to either of these two values. The code only appeared to work because
tg3 initializes active_speed to SPEED_INVALID during tg3_init_one. This
patch introduces a new "old_link" tg3 member and then compares the
phy_device's link member against it to detect link state changes.

efx_for_each_possible_channel_tx_queue() should do nothing for RX-only

We have a very simple way of allocating buffer table entries to
queues, which is just to take the next one available. The extra
channels are the highest numbered channels but they need to be
allocated the lowest entries so that the traffic channels can be
allocated new entries without any collisions.

efx_vfdi_set_status_page() validates the peer page count by
calculating the size of a request containing that many addresses and
comparing that with the maximum valid request size (4KB). The
calculation involves a multiplication that may overflow on a 32-bit
system.
We use kcalloc() to allocate memory to store the addresses; that also
does a multiplication and it does check for integer overflow, so any
values larger than 0x1fffffff will be rejected. However, values in
the range [0x1fffffffc, 0x1fffffff] pass boh tests and result in an
attempt to allocate nearly 4GB on the heap. This should be rejected
rather quickly as it's obviously impossible on a 32-bit system, and
indeed the maximum possible heap allocation is 32MB. Still, let's
make absolutely sure by fixing the initial validation.
Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
This requirement was meant to be implied in the name 'status page'.
One out-of-tree VF driver allocates a buffer using the structure size
and not a full page - hence the current odd specification - but in
practice that allocation will be padded and aligned to at least 4KB.
Therefore, we can specify this and have the option to extend the
structure up to 4KB without worrying about VF drivers using odd-shaped
buffers.

The patch integrates FW 7.2.16 HSI and implements driver
part of GRO flow.
FW 7.2.16 adds the ability to aggregate packets for GRO
(and not just LRO) and also fixes some bugs.
1. Added new aggregation mode: GRO. In this mode packets are aggregated
such that the original packets can be reconstructed by the OS.
2. 57712 HW bug workaround - initialized all CAM TM registers to 0x32.
3. Adding the FCoE statistics structures to the BNX2X HSI.
4. Wrong configuration of TX HW input buffer size may cause theoretical
performance effect. Performed configuration fix.
5. FCOE - Arrival of packets beyond task IO size can lead to crash.
Fix firmware data-in flow.
6. iSCSI - In rare cases of on-chip termination the graceful termination
timer hangs, and the termination doesn't complete. Firmware fix to MSL
timer tolerance.
7. iSCSI - Chip hangs when target sends FIN out-of-order or with isles
open at the initiator side. Firmware implementation corrected to drop
FIN received out-of-order or with isles still open.
8. iSCSI - Chip hangs when in case of retransmission not aligned to 4-bytes
from the beginning of iSCSI PDU. Firmware implementation corrected
to support arbitrary aligned retransmissions.
9. iSCSI - Arrival of target-initiated NOP-IN during intense ISCSI traffic
might lead to crash. Firmware fix to relevant flow.
