This is in preparation for upcoming patches in the series.
Driver has to expose more threshold temperatures through the
hwmon sysfs interface. More code will be added and do not
want to overload bnxt.c.

Driver currently does hwmon device register and unregister
in open and close() respectively. As a result, user will not
be able to query hwmon temperature when interface is in
ifdown state.
Enhance it by moving the hwmon register/unregister to the
probe/remove functions.

In some OVS environments the TCP pseudo header checksum may need to be
recomputed. Currently this is only done when the interface instance is
configured for "Trunk Mode". We found the issue also occurs in some
Kubernetes environments, these environments do not use "Trunk Mode",
therefor the condition is removed.
Performance tests with this change show only a fractional decrease in
throughput (< 0.2%).

The k3_udma_glue_tx_get_irq() function currently returns negative error
codes on error, zero on error and positive values for success. This
complicates life for the callers who need to propagate the error code.
Also GCC will not warn about unsigned comparisons when you check:
if (unsigned_irq <= 0)
All the callers have been fixed now but let's just make this easy going
forward.

The iAVF txrx hotpath code has several functions that are marked as
"static inline" in the iavf_txrx.c file. This use of inline is frowned
upon in the netdev community and explicitly marked as something to avoid
in the Linux coding-style document (section 15).
Even though these functions are only used once, it is expected that GCC
is smart enough to decide when to perform function inlining where
appropriate without the "hint".
./scripts/bloat-o-meter is showing zero difference with this changes.

As the comment in struct rtnl_link_stats64, rx_dropped should not
include packets dropped by the device due to buffer exhaustion.
They are counted in rx_missed_errors, procfs folds those two counters
together.
Add rx_missed_errors for buffer exhaustion, rx_missed_errors corresponds
to rx_discards, rx_dropped corresponds to rx_discards_other.

As we don't specify the MTU in the driver, the framework
will fall back to 1500 bytes and this doesn't work very
well when we try to attach a DSA switch:
eth1: mtu greater than device maximum
ixp4xx_eth c800a000.ethernet eth1: error -22 setting
MTU to 1504 to include DSA overhead
I checked the developer docs and the hardware can actually
do really big frames, so update the driver accordingly.

The flexible structure (a structure that contains a flexible-array member
at the end) `qed_ll2_tx_packet` is nested within the second layer of
`struct qed_ll2_info`:
struct qed_ll2_tx_packet {
...
/* Flexible Array of bds_set determined by max_bds_per_packet */
struct {
struct core_tx_bd *txq_bd;
dma_addr_t tx_frag;
u16 frag_len;
} bds_set[];
};
struct qed_ll2_tx_queue {
...
struct qed_ll2_tx_packet cur_completing_packet;
};
struct qed_ll2_info {
...
struct qed_ll2_tx_queue tx_queue;
struct qed_ll2_cbs cbs;
};
The problem is that member `cbs` in `struct qed_ll2_info` is placed just
after an object of type `struct qed_ll2_tx_queue`, which is in itself
an implicit flexible structure, which by definition ends in a flexible
array member, in this case `bds_set`. This causes an undefined behavior
bug at run-time when dynamic memory is allocated for `bds_set`, which
could lead to a serious issue if `cbs` in `struct qed_ll2_info` is
overwritten by the contents of `bds_set`. Notice that the type of `cbs`
is a structure full of function pointers (and a cookie :) ):
include/linux/qed/qed_ll2_if.h:
107 typedef
108 void (*qed_ll2_complete_rx_packet_cb)(void *cxt,
109 struct qed_ll2_comp_rx_data *data);
110
111 typedef
112 void (*qed_ll2_release_rx_packet_cb)(void *cxt,
113 u8 connection_handle,
114 void *cookie,
115 dma_addr_t rx_buf_addr,
116 bool b_last_packet);
117
118 typedef
119 void (*qed_ll2_complete_tx_packet_cb)(void *cxt,
120 u8 connection_handle,
121 void *cookie,
122 dma_addr_t first_frag_addr,
123 bool b_last_fragment,
124 bool b_last_packet);
125
126 typedef
127 void (*qed_ll2_release_tx_packet_cb)(void *cxt,
128 u8 connection_handle,
129 void *cookie,
130 dma_addr_t first_frag_addr,
131 bool b_last_fragment, bool b_last_packet);
132
133 typedef
134 void (*qed_ll2_slowpath_cb)(void *cxt, u8 connection_handle,
135 u32 opaque_data_0, u32 opaque_data_1);
136
137 struct qed_ll2_cbs {
138 qed_ll2_complete_rx_packet_cb rx_comp_cb;
139 qed_ll2_release_rx_packet_cb rx_release_cb;
140 qed_ll2_complete_tx_packet_cb tx_comp_cb;
141 qed_ll2_release_tx_packet_cb tx_release_cb;
142 qed_ll2_slowpath_cb slowpath_cb;
143 void *cookie;
144 };
Fix this by moving the declaration of `cbs` to the middle of its
containing structure `qed_ll2_info`, preventing it from being
overwritten by the contents of `bds_set` at run-time.
This bug was introduced in 2017, when `bds_set` was converted to a
one-element array, and started to be used as a Variable Length Object
(VLO) at run-time.

When the master device is unbinded, make sure to clean up all of the
steering rules or flow tables that were created over the master, in
order to allow proper unbinding of master, and for ethernet traffic
to continue to work independently.
Upon bringing master device back up and attaching the slave to it,
checks if the slave already has IPsec configured and if so reconfigure
the rules needed to support RoCE traffic.
Note that while master device is unbound, the user is unable to
configure IPsec again, since they are in a kind of illegal state in
which they are in MPV mode but the slave has no master.
However if IPsec was configured before hand, it will continue to work
for ethernet traffic while master is unbound, and would continue to

zone binding
Extend the list of allowed external cooling devices for thermal zone
binding to include devices of type "emc2305".
The motivation is to provide support for the system SN2201, which is
equipped with the Spectrum-1 ASIC.
The system's airflow control is managed by the EMC2305 RPM-based PWM
Fan Speed Controller as the cooling device.

The MTBR register is used to read temperatures from multiple sensors in
one transaction, but the driver only reads from a single sensor in each
transaction.
Rrestrict the payload size of the MTBR register to prevent the
transmission of redundant data to the firmware.

In the pathological case of building sky2 with 16k PAGE_SIZE, the
frag_addr[] array would never be used, so the original code was correct
that size should be 0. But the compiler now gets upset with 0 size arrays
in places where it hasn't eliminated the code that might access such an
array (it can't figure out that in this case an rx skb with fragments
would never be created). To keep the compiler happy, make sure there is
at least 1 frag_addr in struct rx_ring_info:

The second parameter of stmmac_pltfr_init() needs the pointer of
"struct plat_stmmacenet_data". So, correct the parameter typo when calling the
function.
Otherwise, it may cause this alignment exception when doing suspend/resume.

When the PF and VF drivers both support flexible rx descriptors and have
negotiated the VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC capability, the VF driver
queries the PF for the list of supported descriptor formats
(VIRTCHNL_OP_GET_SUPPORTED_RXDIDS). The PF driver is supposed to set the
supported_rxdids bits that correspond to the descriptor formats the
firmware implements. The legacy 32-byte rx desc format is always
supported, even though it is not expressed in GLFLXP_RXDID_FLAGS.
The ice driver does not advertise the legacy 32-byte rx desc support,
which leads to this failure to bring up the VF using the Intel
out-of-tree iavf driver:
iavf 0000:41:01.0: PF does not list support for default Rx descriptor format
...
iavf 0000:41:01.0: PF returned error -5 (VIRTCHNL_STATUS_ERR_PARAM) to our request 6
The in-tree iavf driver does not expose this bug, because it does not
yet implement VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC.
The ice driver must always set the ICE_RXDID_LEGACY_1 bit in
supported_rxdids. The Intel out-of-tree ice driver and the ice driver in
DPDK both do this.
I copied this piece of the code and the comment text from the Intel
out-of-tree driver.
