Phy accessor functions should live closer to where the base phy read / write routines are. Signed-off-by:

Matt Carlson authored
When tg3 was new, phy accesses through ioctl were allowable at any time. Then, the driver started shutting down the phy when the device was closed. Phy accesses would be allowed when the driver first attached to the device, but then would be forbidden after the device had been up'd and down'd. After that, management firmware made it illegal to access the phy unless the driver "owned" the device. Now that most firmware is being moved over to the APE, it is less clear when phy accesses are safe. While it is possible to attempt to identify these conditions and code the driver to navigate through the pitfalls, it could be perplexing to the admin why phy accesses work in some cases and not others. This patch brings some uniformity to the problem by only allowing phy accesses while the driver has control of the device. Signed-off-by:

The loopback test assumes all traffic goes to the first rx queue. There is a 1 in 4 chance this won't be true if RSS is enabled though. This patch reprograms the RSS indirection table to route all rx packets to the first queue. Signed-off-by:

The oldest tg3 devices had large rx producer ring BD caches. Back then, it made sense to make the BD cache replenish threshold only a function of the number of rx buffers posted by the driver. Since then, the BD cache sizes have shrunk to 25% of their original size and, in some cases, the ring sizes have quadrupled in size. Under such conditions, static BD cache replenish thresholds no longer match the hardware constraints. This patch attempts to factor in the BD cache size into the bd cache replenish strategy, taking the existing hardware bugs into account. Signed-off-by:

The 5717, 5718, 5719 A0, and 5720 A0 has a bug where the rx_discards statistic counter will increment when dropping unwanted multicast frames. This patch works around the problem by attempting to recreate the data using other means. The resulting value will not be accurate, but it can still serve as a problem indicator. Signed-off-by:

This patch implement event notification SCTP_SENDER_DRY_EVENT. SCTP Socket API Extensions: 6.1.9. SCTP_SENDER_DRY_EVENT When the SCTP stack has no more user data to send or retransmit, this notification is given to the user. Also, at the time when a user app subscribes to this event, if there is no data to be sent or retransmit, the stack will immediately send up this notification. Signed-off-by:

SCTP does not check whether the source address of COOKIE-ECHO chunk is the original address of INIT chunk or part of the any address parameters saved in COOKIE in CLOSED state. So even if the COOKIE-ECHO chunk is from any address but with correct COOKIE, the COOKIE-ECHO chunk still be accepted. If the COOKIE is not from a valid address, the assoc should not be established.

The sctp_endpoint_lookup_assoc() function uses a port hash to lookup the association and then checks to see if any of them are on the current endpoint. However, if the current endpoint is not bound, there can't be any associations on it, thus we can bail early. Signed-off-by:

When pos.v <= (void *)chunk + end - ntohs(pos.p->length) and ntohs(pos.p->length) >= sizeof(sctp_paramhdr_t) these two expressions are all true, pos.v <= (void *)chunk + end - sizeof(sctp_paramhdr_t) *must* be true. This patch removes this kind of redundant check. It's same to _sctp_walk_errors macro. Signed-off-by:

This changes offload setting behaviour to what I think is correct: - offloads set via ethtool mean what admin wants to use (by default he wants 'em all) - offloads set via ioctl() mean what userspace is expecting to get (this limits which admin wishes are granted) - TUN_NOCHECKSUM is ignored, as it might cause broken packets when forwarded (ip_summed == CHECKSUM_UNNECESSARY means that checksum was verified, not that it can be ignored) If TUN_NOCHECKSUM is implemented, it should set skb->csum_* and skb->ip_summed (= CHECKSUM_PARTIAL) for known protocols and let others be verified by kernel when necessary. TUN_NOCHECKSUM handling was introduced by commit f43798c2: tun: Allow GSO using virtio_net_hdr Signed-off-by:

When processing an ACK for ADD_IP parameter, we only release the routes on non-active transports. This can cause a wrong source address to be used. We can release the routes and cause new route lookups and source address selection so that new addresses can be used as source. Additionally, we don't need to lookup routes for all transports at the same time. We can let the transmit code path update the cached route when the transport actually sends something. Signed-off-by:

We allow 0 port when adding new addresses. It only makes sence to allow 0 port when removing addresses. When removing the currently bound port will be used when the port in the address is set to 0. Signed-off-by:

When we have have to remove a transport due to ASCONF, we move the data to a new active path. This can trigger CACC algorithm to not mark that data as missing when SACKs arrive. This is because the transport passed to the CACC algorithm is the one this data is sitting on, not the one it was sent on (that one may be gone). So, by sending the original transport (even if it's NULL), we may start marking data as missing. Signed-off-by:
