2020-05-29mmc: sdhci-esdhc-imx: fix the mask for tuning start pointHaibo Chen
According the RM, the bit[6~0] of register ESDHC_TUNING_CTRL is TUNING_START_TAP, bit[7] of this register is to disable the command CRC check for standard tuning. So fix it here.

If a request is prepared, the dma_map/unmap are done in asynchronous call pre_req (prep_data) and post_req (unprep_data). In this case the dma-mapping is right balanced. But if the request was not prepared, the data->host_cookie is define to zero and the dma_map/unmap must be done in the request. The dma_map is called by mmci_dma_start (prep_data), but there is no dma_unmap in this case. This patch adds dma_unmap_sg when the dma is finalized and the data cookie is zero (request not prepared).

2020-05-29mmc: sdhci-cadence: fix PHY writeVladimir Kondratiev
Accordingly to Cadence documentation, PHY write procedure is: 1. Software sets the PHY Register Address (HRS04[5:0]) and the PHY Write Data (HRS04[15:8]) fields. 2. Software sets the PHY Write Transaction Request (HRS04[24]) field to 1. 3. Software waits as the PHY Write Transaction Acknowledge (HRS04[26]) field is equal to 0. 4. Hardware performs the write transaction to PHY register where HRS04[15:8] is a data written to register under HRS04[5:0] address. 5. Hardware sets the PHY Transaction Acknowledge (HRS04[26]) to 1 when transaction is completed. 6. Software clears the PHY Write Transaction Request (HRS04[24]) to 1 after noticing that the PHY Write Transaction Acknowledge (HRS04[26]) field is equal to 1. 7. Software waits for the PHY Acknowledge Register (HRS04[26]) field is equal to 0. Add missing steps 3 and 7. Lack of these steps causes integrity errors detested by hardware.

Then it will go to xfrm6_local_error() where it tries to get ipv6 info from a ipv4 sk. This issue was actually fixed by Commit 628e341f319f ("xfrm: make local error reporting more robust"), but brought back by Commit 844d48746e4b ("xfrm: choose protocol family by skb protocol"). So to fix it, we should call xfrm6_local_error() only when skb->protocol is htons(ETH_P_IPV6) and skb->sk->sk_family is AF_INET6.

2020-05-28e1000e: Relax condition to trigger reset for ME workaroundPunit Agrawal
It's an error if the value of the RX/TX tail descriptor does not match what was written. The error condition is true regardless the duration of the interference from ME. But the driver only performs the reset if E1000_ICH_FWSM_PCIM2PCI_COUNT (2000) iterations of 50us delay have transpired. The extra condition can lead to inconsistency between the state of hardware as expected by the driver. Fix this by dropping the check for number of delay iterations. While at it, also make __ew32_prepare() static as it's not used anywhere else.

2020-05-28igc: Reject NFC rules with multiple matchesAndre Guedes
The way Rx queue assignment based on mac address, Ethertype and VLAN priority filtering operates in I225 doesn't allow us to properly support NFC rules with multiple matches. Consider the following example which assigns to queue 2 frames matching the address MACADDR *and* Ethertype ETYPE. $ ethtool -N eth0 flow-type ether dst <MACADDR> proto <ETYPE> queue 2 When such rule is applied, we have 2 unwanted behaviors: 1) Any frame matching MACADDR will be assigned to queue 2. It doesn't matter the ETYPE value. 2) Any accepted frame that has Ethertype equals to ETYPE, no matter the mac address, will be assigned to queue 2 as well. In current code, multiple-match filters are accepted by the driver, even though it doesn't support them properly. This patch adds a check for multiple-match rules in igc_ethtool_is_nfc_rule_valid() so they are rejected.
