Given NR_IRQS is 2048 on sparc64, and even 32784 on alpha, 3 digits is not enough to represent interrupt numbers on all architectures. Hence PHY interrupt numbers may be truncated during printing. Increase the buffer size from 4 to 8 bytes to fix this. Fixes: 5e369aef ("net: stmmac: Delete dead code for MDIO registration") Signed-off-by:

Usually socket closing is delayed if there is still data available in the send buffer to be transmitted. If a process is killed, the delay should be avoided. Signed-off-by:

An out-of-sync condition can just be detected by the client. If the server receives a CLC DECLINE message indicating an out-of-sync condition for the link groups, the server must clean up the out-of-sync link group. There is no need for an extra third parameter in smc_clc_send_decline(). Signed-off-by:

Client link group creation always follows the server linkgroup creation. If peer creates a new server link group, client has to create a new client link group. If peer reuses a server link group for a new connection, client has to reuse its client link group as well. This patch introduces a longer delay for client link group removal to make sure this link group still exists, once the peer decides to reuse a server link group. This avoids out-of-sync conditions for link groups. If already scheduled, modify the delay. Signed-off-by:

In the infiniband part, SMC currently uses get_netdev which calls dev_hold on the returned net device. However, the SMC code never calls dev_put on that net device resulting in a wrong reference count. This patch adds a dev_put after the usage of the net device to fix the issue. Signed-off-by:

Use default value of auto duplex and auto speed values loaded from EEPROM/OTP after reset. The LAN78xx allows platform configurations to be loaded from EEPROM/OTP.

Florian Fainelli says: ==================== net: Bring back transceiver type for PHYLIB With the introduction of the xLINKSETTINGS ethtool APIs, the transceiver type was deprecated, but in that process we lost some useful information that PHYLIB was consistently reporting about internal vs. external PHYs. This brings back transceiver as a read-only field that is only consumed in the legacy path where ETHTOOL_GET is called but the underlying drivers implement the new style klink_settings API. ==================== Signed-off-by: -
Florian Fainelli authored
With commit 2d55173e ("phy: add generic function to support ksetting support"), we lost the ability to report the transceiver type like we used to. Now that we have added back the transceiver type to ethtool_link_settings, we can report it back like we used to and have no loss of information.

Commit 3f1ac7a7 ("net: ethtool: add new ETHTOOL_xLINKSETTINGS API") deprecated the ethtool_cmd::transceiver field, which was fine in premise, except that the PHY library was actually using it to report the type of transceiver: internal or external. Use the first word of the reserved field to put this __u8 transceiver field back in. It is made read-only, and we don't expect the ETHTOOL_xLINKSETTINGS API to be doing anything with this anyway, so this is mostly for the legacy path where we do: ethtool_get_settings() -> dev->ethtool_ops->get_link_ksettings() -> convert_link_ksettings_to_legacy_settings() to have no information loss compared to the legacy get_settings API.

The EMAC has the option of sending only a single pause frame when flow control is enabled and the RX queue is full. Although sending only one pause frame has little value, this would allow admins to enable automatic flow control without having to worry about the EMAC flooding nearby switches with pause frames if the kernel hangs. The option is enabled by using the single-pause-mode private flag. Signed-off-by:

If MTU is changed the host would reject the send buffer change. This problem is result of recent change to allow changing send buffer size. Every time we change the MTU, we store the previous net_device section count before destroying the buffer, but we don’t store the previous section size. When we reinitialize the buffer, its size is calculated by multiplying the previous count and previous size. Since we continuously increase the MTU, the host returns us a decreasing count value while the section size is reinitialized to 1728 bytes every time. This eventually leads to a condition where the calculated buf_size is so small that the host rejects it. Fixes: 8b532797 ("netvsc: allow controlling send/recv buffer size") Signed-off-by:

rss_size is 1, 2, 4, 8, 16, 32, 64, 128, but acutal tc queue size can be any u16 less than 128. If tc queue size is 5, we set the rss_size to 8, indirection table will be used to limit the size of actual queue size. It may cause dropping of receiving packet in hardware if rss_size is not set correctly. For now, each TC has the same rss size.

rx_priv_buf_alloc is used to tell hardware how much buffer is used for rx direction, right now only the private buffer is assigned.

In isdn_ppp_write(), the header (i.e., protobuf) of the buffer is fetched twice from userspace. The first fetch is used to peek at the protocol of the message and reset the huptimer if necessary; while the second fetch copies in the whole buffer. However, given that buf resides in userspace memory, a user process can race to change its memory content across fetches. By doing so, we can either avoid resetting the huptimer for any type of packets (by first setting proto to PPP_LCP and later change to the actual type) or force resetting the huptimer for LCP packets. This patch changes this double-fetch behavior into two single fetches decided by condition (lp->isdn_device < 0 || lp->isdn_channel <0).

Since XDP's view of the packet includes the MAC header, moving the start- of-packet with bpf_xdp_adjust_head needs to also update the offset of the MAC header (which is relative to skb->head, not to the skb->data that was changed). Without this, tcpdump sees packets starting from the old MAC header rather than the new one, at least in my tests on the loopback device. Fixes: b5cdae32 ("net: Generic XDP") Signed-off-by:
