The current IRQ coalescing logic is a little messy. The ethtool parameters are mapped to hardware parameters in a way that is difficult to understand. The first step is to better organize the parameters by adding the new structure bnxt_coal. The structure is used by both the RX and TX sets of coalescing parameters. Adjust the default coal_ticks to 14 us and 28 us for RX and TX. Signed-off-by:

The current code retrieves the firmware package version from firmware everytime ethtool -i is run. There is no reason to do that as the firmware will not change while the driver is loaded. Get the version once at init time. Also, display the full 4-part firmware version string and remove the less useful interface spec version. Signed-off-by:

Vivien Didelot says: ==================== net: dsa: define port types The DSA code currently has 3 bitmaps in the dsa_switch structure: cpu_port_mask, dsa_port_mask and enabled_port_mask. They are used to store the type of each switch port. This dates back from when DSA didn't have a dsa_port structure to hold port-specific data. The dsa_switch structure is mainly used to communicate with DSA drivers and must not contain such static data parsed from DTS or pdata, which belongs the DSA core structures, such as dsa_switch_tree and dsa_port. Also the enabled_port_mask is misleading, often misinterpreted as the complement of disabled ports (thus including DSA and CPU ports), while in fact it only masks the user ports. A port can be of 3 types when it is not unused: "cpu" (interfacing with a master device), "dsa" (interconnecting with another "dsa" port from another switch chip), or "user" (user-facing port.) This patchset first fixes the usage of DSA port type helpers, then defines the DSA_PORT_TYPE_UNUSED, DSA_PORT_TYPE_CPU, DSA_PORT_TYPE_DSA, and DSA_PORT_TYPE_USER port types, and finally removes the misleading port bitmaps. ==================== Signed-off-by: -

Now that DSA core provides port types, there is no need to keep this information at the switch level. This is a static information that is part of a DSA core dsa_port structure. Remove them. Signed-off-by:

Now that DSA exposes an enumerated type for the ports, we can use them directly instead of checking bitmaps, which is more consistent. Signed-off-by:
-
Vivien Didelot authored
Introduce an enumerated type for ports, which will be way more explicit to identify a port type instead of digging into switch port masks. A port can be of type CPU, DSA, user, or unused by default. This is a static parsed information that cannot be changed at runtime. Signed-off-by:

Vivien Didelot authored
Introduce a dsa_user_ports() helper to return the ds->enabled_port_mask mask which is more explicit. This will also minimize diffs when touching this internal mask. Signed-off-by:
-
Vivien Didelot authored
Most of the DSA code still check ds->enabled_port_mask directly to inspect a given port type instead of using the provided dsa_is_user_port helper. Change this. Signed-off-by:

This patch renames dsa_is_normal_port to dsa_is_user_port because "user" is the correct term in the DSA terminology, not "normal". Signed-off-by:
-
Vivien Didelot authored
In order to know if a port is of type user, dsa_is_normal_port checks that the given port is not of type DSA nor CPU. This is not enough because a port can be unused. Without the previous fix, this caused the unused mv88e6xxx ports to be configured in normal mode. The ds->enabled_port_mask reports the user ports, so check this instead. Signed-off-by:
-
Vivien Didelot authored
The unused ports are currently configured in normal mode. This does not prevent the switch from being functional, but it is unnecessary. Skip unused ports. Signed-off-by:
-
Vivien Didelot authored
As the comment above the chunk states, the b53 driver attempts to disable the unused ports. But using ds->enabled_port_mask is misleading, because this mask reports in fact the user ports. To avoid confusion and fix this, this patch introduces an explicit dsa_is_unused_port helper which ensures the corresponding bit is not masked in any of the switch port masks. Signed-off-by:

Egil Hjelmeland says: ==================== net: dsa: lan9303: Learn addresses on CPU port when bridged When CPU transmit directly to port using tag, the LAN9303 does not learn MAC addresses received on the CPU port into the ALR table. ALR learning is performed only when transmitting using ALR lookup. Solution: If the two external ports are bridged and the packet is not STP BPDU, then use ALR lookup to allow ALR learning on CPU port. Otherwise transmit directly to port with STP state override. The first patch moves struct lan9303 to include/linux/dsa/lan9303.h in order to prepare for the second patch. Changes v1 -> v2: - new file: include/linux/dsa/lan9303.h instead of include/linux/lan9303.h - include linux/if_ether.h in include/linux/dsa/lan9303.h - renamed lan9303_tx_use_arl to lan9303_xmit_use_arl for consistency. - removed inline keyword to lan9303_xmit_use_arl ==================== Signed-off-by: -

commit afdb09c7 ("security: bpf: Add LSM hooks for bpf object related syscall") included linux/bpf.h in linux/security.h. As a result, bpf programs including bpf_helpers.h and some other header that ends up pulling in also security.h, such as several examples under samples/bpf, fail to compile because bpf_tail_call and bpf_get_stackid are now "redefined as different kind of symbol". >From bpf.h: u64 bpf_tail_call(u64 ctx, u64 r2, u64 index, u64 r4, u64 r5); u64 bpf_get_stackid(u64 r1, u64 r2, u64 r3, u64 r4, u64 r5); Whereas in bpf_helpers.h they are: static void (*bpf_tail_call)(void *ctx, void *map, int index); static int (*bpf_get_stackid)(void *ctx, void *map, int flags); Fix this by removing the unused declaration of bpf_tail_call and moving the declaration of bpf_get_stackid in bpf_trace.c, which is the only place where it's needed.

Deprecate the 1-bit flag (bit 2 in the SLI_SCRATCH_1 Octeon register) that indicates that the liquidio watchdog kernel thread is running for this NIC. Reason is: it is incompatible with the firmware's use for SLI_SCRATCH_1. In lieu of checking that now-deprecated flag, check the value of oct_dev->adapter_refcount to determine whether or not to create the watchdog kernel thread. Signed-off-by:
