In new NICs flash is managed by firmware and we will use high-level operations on partitions rather than direct SPI commands. Add support for multiple MTD partitions per flash device and remove the direct link between MTD and SPI devices. Maintain a list of MTD partitions in struct efx_nic. Signed-off-by:

New NICs have firmware managing the PHY, and we will discover the PHY capabilities at run-time. Replace the static data with probe() and test_name() operations. Signed-off-by:

falcon_probe_nic_variant() does a lot less than it used to, and a lot less than it claims to. Fold the remainder into its caller. Signed-off-by:

Refactor PHY, MAC and NIC configuration operations so that the existing link configuration can be re-pushed with: efx->phy_op->reconfigure(efx); efx->mac_op->reconfigure(efx); and a new configuration with: efx->nic_op->reconfigure_port(efx); (plus locking and error-checking). We have not held the link settings in software (aside from flow control), and have relied on asking the hardware what they are. This is a problem because in some cases the hardware may no longer be in a state to tell us. In particular, if an entire multi-port board is reset through one port, the driver bindings to other ports have no chance to save settings before recovering. We only actually need to keep track of the autonegotiation settings, so add an ethtool advertising mask to struct efx_nic, initialise it in PHY init and update it as necessary. Remove now-unneeded uses of efx_phy_op::{get,set}_settings() and struct ethtool_cmd. Much of this was done by Steve Hodgson <shodgson@solarflare.com>. Signed-off-by: -

Pause frame generation is gated by both RX_XOFF_MAC_EN and an enable bit in each MAC. RX_XOFF_MAC_EN bit always reads back as 0 so we need to set it correctly every time we modify RX_CFG_REG. Simplify this by always setting it to 1 and only changing the enable bits in the MACs. Signed-off-by:

This patch extends the ethtool interface to display what PHY is currently connected to a NIC. The results can be viewed in ethtool ethX output. Signed-off-by:

Flow Control autoneg should be disabled for certain adapters that don't support autonegotiation of Flow Control at 10 gigabit. These interfaces are the 10GBASE-T devices, CX4, and SFP+, all running at 10 gigabit only. 1 gigabit is fine. Signed-off-by:

The driver was doing a divide by zero when adjusting tx-usecs. This patch removes the divide by zero code and changes the logic slightly to ignore tx-usecs in the case of shared TxRx vectors. Cc: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by:

Reading standard registers on the QT2025C before its firmware has booted may cause the boot process to fail. Therefore, follow the recommended reset sequence before reading its id registers. Either order works for the QT2022C2, so don't differentiate. Signed-off-by:

Falcon can generate events for LASI interrupts from the PHY, but in practice we have never implemented this in reference designs. Instead we have polled, inserted the appropriate events, and then handled the events later. This is a waste of time and code. Instead, make PHY poll functions update the link state synchronously and report whether it changed. We can still make use of the LASI registers as a shortcut on the SFT9001. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> Currently we can set multicast hash immediately (in atomic context) but must delay setting MAC promiscuity. There is not that much point in deferring one but not the other, and setting the multicast hash on Siena will involve a firmware request. So process them both in efx_mac_work(). Also, set the broadcast bit in the multicast hash in efx_set_multicast_list(), since this is required for both Falcon and Siena. Signed-off-by:

From: Steve Hodgson <shodgson@solarflare.com> Only the XMAC on Falcon needs help from the driver to poll and reset the MAC-PHY link (XAUI); GMII is a simple parallel bus and on later NICs firmware takes care of the XAUI link. Also, an XMAC interrupt currently schedules a work item which simply clears a flag (efx_nic::mac_up) to be checked by the regular monitor (or the next link reconfiguration, if that is sooner). Rename the flag to xmac_poll_required, changing its sense. Remove the needless indirection and just set the flag immediately. Call falcon_xmac_poll() directly where required. Add a new generic operation mac_op::check_fault to check the link outside of regular monitoring, as required during self-tests. (Note that this leaves us with an unused work item, but we will immediately have another use for it.) Signed-off-by:
