Ethernet frame consists of - Ethernet header, payload, FCS. The MTU value which is used by user is the size of the payload, which means that when user sets MTU to X, the total frame size will be larger due to the addition of the Ethernet header and FCS. Spectrum ASICs take into account Ethernet header and FCS as part of packet size for MTU check. Adjust MTU value when user sets MTU, to configure the MTU size which is required by hardware. The Tx header length which was used by the driver is not relevant for such calculation, take into account Ethernet header (with VLAN extension) and FCS. Signed-off-by:

Russell King says: ==================== net: stmmac: provide platform select_pcs method This series adds a select_pcs() method to the stmmac platform data to allow platforms that need to provide their own PCSes to do so, moving the decision making into platform code. This avoids questions such as "what should the priority of XPCS vs some other platform PCS be?" and when we provide a PCS for the internal PCS, how that interacts with both the XPCS and platform provided PCS. Note that if a platform implements the select_pcs() method, then the return values are: - a phylink_pcs pointer - the PCS to be used. - NULL - no phylink_pcs to be used. Otherwise (if not implemented or returns an error-pointer), then allow the the stmmac internal PCS to be used if appropriate (once that patch set is merged.) Patch 1 introduces the new method. Patch 2 converts Intel mGBE to use this to provide the XPCS and removes the XPCS decision making from core code. Patch 3 provides an implementation for rzn1 to return its PCS. Patch 4 does the same for socfpga. Patch 5 removes the core code returning priv->hw->phylink_pcs. No functional change is anticipated. Once this has been merged, it will be expected that platforms should populate all three PCS methods or none of the PCS methods. ==================== Link: https://lore.kernel.org/r/ZmrLbdwv6ALoy+gs@shell.armlinux.org.ukSigned-off-by:

Since all platform providers of PCS now populate the select_pcs() method, there is no need for the common code to look at priv->hw->phylink_pcs, so remove it. Reviewed-by:

Currently a ct entry is stored in both ct and ct-nat tables. ct action is directed to the ct table, while ct nat action is directed to the nat table. ct-nat entries perform the nat header rewrites, if required. The current design assures that a ct action will match in hardware even if the tuple has nat configured, it will just not execute it. However, storing each connection in two tables increases the system's memory consumption while reducing its insertion rate. Offload a connection to either ct or the ct-nat table. Add a miss fall-through rule from ct-nat table to the ct table allowing ct(nat) action on non-natted connections. ct action on natted connections, by default, will be handled by the software miss path.

Ignore the ENODEV failures returned by kernel_sendmsg(). These errors indicate that either the local port has been closed or the remote has gone down. Neither of these scenarios are fatal and will eventually be handled through packets that are later queued on the control port. Signed-off-by:

Pull the external clock selector into a separate function, to avoid conflating it with external clock rate validation and clock mux register configuration. This should make the code easier to read and understand. The dwmac->enable_eth_ck variable in the end indicates whether the MAC clock are supplied by external oscillator (true) or internal RCC clock IP (false). The dwmac->enable_eth_ck value is set based on multiple DT properties, some of them deprecated, some of them specific to bus mode. The following DT properties and variables are taken into account. In each case, if the property is present or true, MAC clock is supplied by external oscillator. - "st,ext-phyclk", assigned to variable dwmac->ext_phyclk - Used in any mode (MII/RMII/GMII/RGMII) - The only non-deprecated DT property of the three - "st,eth-clk-sel", assigned to variable dwmac->eth_clk_sel_reg - Valid only in GMII/RGMII mode - Deprecated property, backward compatibility only - "st,eth-ref-clk-sel", assigned to variable dwmac->eth_ref_clk_sel_reg - Valid only in RMII mode - Deprecated property, backward compatibility only The stm32mp1_select_ethck_external() function handles the aforementioned DT properties and sets dwmac->enable_eth_ck accordingly. The stm32mp1_set_mode() is adjusted to call stm32mp1_select_ethck_external() first and then only use dwmac->enable_eth_ck to determine hardware clock mux settings. No functional change intended.

Pull the external clock frequency validation into a separate function, to avoid conflating it with external clock DT property decoding and clock mux register configuration. This should make the code easier to read and understand. This does change the code behavior slightly. The clock mux PMCR register setting now depends solely on the DT properties which configure the clock mux between external clock and internal RCC generated clock. The mux PMCR register settings no longer depend on the supplied clock frequency, that supplied clock frequency is now only validated, and if the clock frequency is invalid for a mode, it is rejected. Previously, the code would switch the PMCR register clock mux to internal RCC generated clock if external clock couldn't provide suitable frequency, without checking whether the RCC generated clock frequency is correct. Such behavior is risky at best, user should have configured their clock correctly in the first place, so this behavior is removed here. Signed-off-by:
