In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.
Use struct_group() in struct nig_stats around members egress_mac_pkt0_lo,
egress_mac_pkt0_hi, egress_mac_pkt1_lo, and egress_mac_pkt1_hi (and the
respective members in struct bnx2x_eth_stats), so they can be referenced
together. This will allow memcpy() and sizeof() to more easily reason
about sizes, improve readability, and avoid future warnings about writing
beyond the end of struct bnx2x_eth_stats's rx_stat_ifhcinbadoctets_hi.
"pahole" shows no size nor member offset changes to either struct.
"objdump -d" shows no meaningful object code changes (i.e. only source
line number induced differences and optimizations).
Additionally adds BUILD_BUG_ON() to compare the separate struct group
sizes.

This patch introduces a NAPI-style approach for processing completed
Rx URBs that contributes to improving driver throughput and reducing
CPU load.
Packets in completed URBs are copied to NAPI SKBs and passed to the
network stack for processing. Each frame passed to the stack is one
work item in the NAPI budget.
If the NAPI budget is consumed and frames remain, they are added to
an overflow queue that is processed at the start of the next NAPI
polling cycle.
The NAPI handler is also responsible for copying pending Tx data to
Tx URBs and submitting them to the USB host controller for
transmission.

This patch introduces a new approach to allocating and managing
Rx URBs that contributes to improving driver throughput and reducing
CPU load.
A pool of Rx URBs is created during driver instantiation. All the
URBs are initially submitted to the USB host controller for
processing.
The default URB buffer size is different for each USB bus speed.
The chosen sizes provide good USB utilisation with little impact on
overall packet latency.
Completed URBs are processed in the driver bottom half. The URB
buffer contents are copied to a dynamically allocated SKB, which is
then passed to the network stack. The URB is then re-submitted to
the USB host controller.
NOTE: the call to skb_copy() in rx_process() that copies the URB
contents to a new SKB is a temporary change to make this patch work
in its own right. This call will be removed when the NAPI processing
is introduced by patch 6 in this patch set.

This patch introduces a new approach to allocating and managing
Tx URBs that contributes to improving driver throughput and reducing
CPU load.
A pool of Tx URBs is created during driver instantiation. A URB is
allocated from the pool when there is data to transmit. The URB is
released back to the pool when the data has been transmitted by the
device.
The default URB buffer size is different for each USB bus speed.
The chosen sizes provide good USB utilisation with little impact on
overall packet latency.
SKBs to be transmitted are added to a pending queue for processing.
The driver tracks the available Tx URB buffer space and copies as
much pending data as possible into each free URB. Each full URB
is then submitted to the USB host controller for transmission.

PSFP rules take effect on the streams from any port of VSC9959 switch.
This patch use ingress port to limit the rule only active on this port.
Each stream can only match two ingress source ports in VSC9959. Streams
from lowest port gets the configuration of SFID pointed by MAC Table
lookup and streams from highest port gets the configuration of (SFID+1)
pointed by MAC Table lookup. This patch defines the PSFP rule on highest
port as dummy rule, which means that it does not modify the MAC table.

VSC9959 supports Per-Stream Filtering and Policing(PSFP) that complies
with the IEEE 802.1Qci standard. The stream is identified by Null stream
identification(DMAC and VLAN ID) defined in IEEE802.1CB.
For PSFP, four tables need to be set up: stream table, stream filter
table, stream gate table, and flow meter table. Identify the stream by
parsing the tc flower keys and add it to the stream table. The stream
filter table is automatically maintained, and its index is determined by
SGID(flow gate index) and FMID(flow meter index).

The definition of macro MOTO_SROM_BUG is:
#define MOTO_SROM_BUG (lp->active == 8 && (get_unaligned_le32(
dev->dev_addr) & 0x00ffffff) == 0x3e0008)
and the if statement
if (MOTO_SROM_BUG) lp->active = 0;
using this macro indicates lp->active could be 8. If lp->active is 8 and
the second comparison of this macro is false. lp->active will remain 8 in:
lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1);
lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1);
lp->phy[lp->active].mc = get_unaligned_le16(p); p += 2;
lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2;
lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2;
lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2;
lp->phy[lp->active].mci = *p;
However, the length of array lp->phy is 8, so array overflows can occur.
To fix these possible array overflows, we first check lp->active and then
return -EINVAL if it is greater or equal to ARRAY_SIZE(lp->phy) (i.e. 8).

10GbE Intel Wired LAN Driver Updates 2021-11-17
Radoslaw Tyl says:
The change is a consequence of errors reported by the ixgbevf driver
while starting several virtual guests at the same time on ESX host.
During this, VF was not able to communicate correctly with the PF,
as a result reported "PF still in reset state. Is the PF interface up?"
and then goes to locked state. The only thing left was to reload
the VF driver on the guest OS.
The background of the problem is that the current PFU and VFU
semaphore locking mechanism between sender and receiver may cause
overriding Mailbox memory (VFMBMEM), in such scenario receiver of
the original message will read the invalid, corrupted or one (or more)
message may be lost.
This change is actually as a support for communication with PF ESX
driver and does not contains changes and support for ixgbe driver.
For maintain backward compatibility, previous communication method
has been preserved in the form of LEGACY functions.
In the future there is a plan to add a support for a 1.5 mailbox API
communication also to ixgbe driver.
