The comment is correct, but the code ends up moving the bits four places too far, into the VTUOp field.

2019-06-18net: mvpp2: cls: Add steering based on vlan Id and priority.Maxime Chevallier2-34/+86
This commit allows using the vlan Id and priority as parts of the key for classification offload. These fields are extracted from the outermost tag, if multiple tags are present. Vlan Id and priority are considered as 2 different fields by the classifier, however the fields are both appended in the Header Extracted Key in the same layout as they are found in the tags. This means that when steering only based on the prio, a 16-bit slot is still taken in the HEK. The classifier doesn't allow extracting the DEI bit from the tag, so we explicitly prevent user from using this bit in the key. This commit adds the vlan priotity as a compatible HEK field for tagged traffic, meaning that we limit the possibility of extracting this field only to the flows that contain tagged traffic.

2019-06-18net: mvpp2: cls: right-justify the C2 TCAM keysMaxime Chevallier1-7/+7
The C2 TCAM used for classification uses a key (Header Extracted Key) built by concatenating several fields extracted from the packet header. After a lot of trial-and-error and some guess work, it seems the HEK is right justified, with the first fields being stored in the MSB, then concatenated up until the LSB. Until now, this doesn't cause any issue since all HEK fields we use are full bytes. However this is an issue for the upcoming VLAN id and pri extraction, which aren't full bytes. Rework the way we built that TCAM key, by changing the order in which we append the fields. Signed-off-by: Maxime Chevallier <maxime.chevallier@bootlin.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-06-18net: mvpp2: cls: Only select applicable flows of classification offloadMaxime Chevallier1-0/+3
The way we currently handle classification offload and RSS is by having dedicated lookup sequences in the flow table, each being selected depending on several fields being present in the packet header. We need to make sure the classification operation we want to perform can be done in each flow we want to insert it into. As an example, classifying on VLAN tag can only be done on flows used for tagged traffic. This commit makes sure we don't insert rules in flows we aren't compatible with.

2019-06-18net: mvpp2: cls: Use a dedicated lu_type for the RSS lookupMaxime Chevallier2-2/+7
When performing a TCAM lookup in the C2 engine, it's possible that multiple entries match the packet. To make sure the correct entry match when performing a lookup, the Flow Table can set a lookup type, which will be used in the TCAM lookup, thus preventing such false-positives. We need to make sure the RSS match doesn't interfere with other classification lookups, hence we use a dedicated lookup_type for it.

2019-06-18macb: Add support for SiFive FU540-C000Yash Shah1-0/+123
The management IP block is tightly coupled with the Cadence MACB IP block on the FU540, and manages many of the boundary signals from the MACB IP. This patch only controls the tx_clk input signal to the MACB IP. Future patches may add support for monitoring or controlling other IP boundary signals.

Add the compatibility string documentation for SiFive FU540-C0000 interface. On the FU540, this driver also needs to read and write registers in a management IP block that monitors or drives boundary signals for the GEMGXL IP block that are not directly mapped to GEMGXL registers. Therefore, add additional range to "reg" property for SiFive GEMGXL management IP registers.

2019-06-18qed: Fix -Wmaybe-uninitialized false positiveArnd Bergmann1-0/+1
A previous attempt to shut up the uninitialized variable use warning was apparently insufficient. When CONFIG_PROFILE_ANNOTATED_BRANCHES is set, gcc-8 still warns, because the unlikely() check in DP_NOTICE() causes it to no longer track the state of all variables correctly: drivers/net/ethernet/qlogic/qed/qed_dev.c: In function 'qed_llh_set_ppfid_affinity': drivers/net/ethernet/qlogic/qed/qed_dev.c:798:47: error: 'abs_ppfid' may be used uninitialized in this function [-Werror=maybe-uninitialized] addr = NIG_REG_PPF_TO_ENGINE_SEL + abs_ppfid * 0x4; ~~~~~~~~~~^~~~~ This is not a nice workaround, but always initializing the output from qed_llh_abs_ppfid() at least shuts up the false positive reliably.
