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:

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: -

Add 'likely' hint to test of rx_checksum_enabled. Don't count IP fragments; the IP stack can do that. Do count non-matching multicast packets. Signed-off-by:

The strap bits are only important on Falcon A and all production boards using it have fixed-speed 10G PHYs. Replace dummy MAC operations with default MAC operations. Signed-off-by:

We never use MDIO in atomic context, so we don't need to spin. 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:

From: Steve Hodgson <shodgson@solarflare.com> Currently we initiate MAC stats DMA and busy-wait for completion when stats are requested. We can improve on this with a periodic timer to initiate and poll for stats, and opportunistically poll when stats are requested. Since efx_nic::stats_disable_count and efx_stats_{disable,enable}() are Falcon-specific, rename them and move them accordingly. Signed-off-by: -

Avoid overrunning the hardware limit of 4 concurrent RX queue flushes. Expand the queue flush state to support this. Make similar changes to TX flushing to keep the code symmetric. Signed-off-by:

Rename struct efx_board to struct falcon_board. Introduce and use inline function to look up board info from struct efx_nic, in preparation for moving it. Move board init and fini calls into NIC probe and remove functions. Signed-off-by:

efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split. Signed-off-by:

Only some PHYs have firmware support for a LED blink mode, so we currently blink the others in a timer function. Since all PHYs have simple on and off modes, we don't gain anything by using multiple blink implementations. Also, since we have a process context there is no need to use a timer. Signed-off-by:

Received frames must be re-clocked by the local XGXS to the 156.25 MHz (DDR) clock of the XGMII. If the remote clock is slightly faster this can reduce a minimum IPG of 64 bit-times (1 cycle) to 32 bit-times (half a cycle). If the XMAC detects that a frame has reached the maximum RX frame length in the same cycle that it receives one of these reduced IPGs, it may miss the IPG, causing two valid frames to be treated as a single invalid frame (over-length with bad CRC). We work around this by increasing the maximum RX frame length so that peers with matched MTU will not provoke this bug. Signed-off-by:
