It turns out that the "Workaround for putting the PHY in IDDQ mode" used by the internal EPHYs on 40nm Set-Top Box chips when powering down puts the interface to the GENET MAC in a state that can cause subsequent MAC resets to be incomplete. Rather than restore the forced soft reset when powering up internal PHYs, this commit moves the invocation of phy_init_hw earlier in the MAC initialization sequence to just before the MAC reset in the open and resume functions. This allows the interface to be stable and allows the MAC resets to be successful. The bcmgenet_mii_probe() function is split in two to accommodate this. The new function bcmgenet_mii_connect() handles the first half of the functionality before the MAC initialization, and the bcmgenet_mii_config() function is extended to provide the remaining PHY configuration following the MAC initialization.

When using the fixed PHY with GENET (e.g. MOCA) the PHY link status can be determined from the internal link status captured by the MAC.

There were a number of issues with setting the RX coalescing parameters: - we would not be preserving values that would have been configured across close/open calls, instead we would always reset to no timeout and 1 interrupt per packet, this would also prevent DIM from setting its default usec/pkts values - when adaptive RX would be turned on, we woud not be fetching the default parameters, we would stay with no timeout/1 packet per interrupt until the estimator kicks in and changes that - finally disabling adaptive RX coalescing while providing parameters would not be honored, and we would stay with whatever DIM had previously determined instead of the user requested parameters Fixes: 9f4ca058 ("net: bcmgenet: Add support for adaptive RX coalescing") Signed-off-by: NFlorian Fainelli <f.fainelli@gmail.com> Reviewed-by: NTal Gilboa <talgi@mellanox.com> Signed-off-by: NDavid S.

Now that the software reset of the PHY has been removed it is no longer necessary to retain a private pointer to the phydev for use when the PHY is detached (which isn't generally safe anyway). The driver now uses the phydev member attached to the net_device. For ethtool commands that have a PHY component, an explicit check is made to prevent accessing an invalid phydev pointer when one is not attached (e.g. interface is down).

Since the skb is attached to the first control block of a fragmented skb it is possible that the skb could be freed when reclaiming that control block before all fragments of the skb have been consumed by the hardware and unmapped. This commit introduces first_cb and last_cb pointers to the skb control block used by the driver to keep track of which transmit control blocks within a transmit ring are the first and last ones associated with the skb. It then splits the bcmgenet_free_cb() function into transmit (bcmgenet_free_tx_cb) and receive (bcmgenet_free_rx_cb) versions that can handle the unmapping of dma mapped memory and cleaning up the corresponding control block structure so that the skb is only freed after the last associated transmit control block is reclaimed.

When bcmgenet device uses Tx checksum offload, each transmitted skb gets an extra 64-byte header prepended to it. Before this header is prepended to the skb, we need to save the skb "wire" length in GENET_CB(skb)->bytes_sent, so that proper Tx bytes accounting can be done in __bcmgenet_tx_reclaim(). 3. skb->len covers the entire length of skb, whether it is linear or fragmented.

Configuring the ethtool tx-frames property, which translates into N packets before a TX interrupt is the simplest configuration scheme because it requires no locking neither at the softare nor hardware level, and is completely indepedent from the link speed. Since ethtool does not allow per-tx queue coalescing parameters, we apply the same setting to any transmit queue. We can no longer enable the BDONE/PDONE interrupts as those would fire for each packet/buffer received, which would defeat the MBDONE interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a PDONE/BDONE interrupt when the threshold is set to 1, but offers interrupt coalescing when the value is > 1. Since the HW is configured to generate an interrupt when the ring becomes emtpy, we have to deny any timeout/timer settings coming from user-space to indicate we can only generate an interrupt very <N> packets.

We are currently doing a full PHY initialization and even starting the pHY state machine during bcmgenet_mii_init() which is executed in the driver's probe function. This is convenient to determine whether we can attach to a proper PHY device but comes at the expense of spending up to 10ms per MDIO transactions (to reach the waitqueue timeout), which slows things down. This also creates a sitaution where we end-up attaching twice to the PHY, which is not quite correct either. Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update its error path accordingly. Avoid printing the message "attached PHY at address 1 [...]" every time we bring up/down the interface and remove this print since it duplicates what the PHY driver already does for us.

Our internal GPHY might be powered off before we attempt scanning the MDIO bus and bind a driver to it. The way we are currently determining whether a PHY is internal or not is done *after* we have successfully matched its driver. If the PHY is powered down, it will not respond to the MDIO bus, so we will not be able to bind a driver to it. Our Device Tree for GENET interfaces specifies a "phy-mode" value: "internal" which tells if this internal uses an internal PHY or not. If of_get_phy_mode() fails to parse the 'phy-mode' property, do an additional manual lookup, and if we find "internal" set the corresponding internal variable accordingly. Replace all uses of phy_is_internal() with a check against priv->internal_phy to avoid having to rely on whether or not priv->phydev is set correctly.

All BCM7xxx integrated Gigabit PHYs have an issue in their MDIO management controller which will make the initial read or write to them to fail and return 0xffff. This is a real issue as the typical first thing we do is read from MII_PHYSID1 and MII_PHYSID2 from get_phy_id() to register a driver for these PHYs. Coupled with the workaround in drivers/net/phy/bcm7xxx.c, this workaround for the MDIO bus controller consists in scanning the list of PHYs to do this initial read workaround for as part of the MDIO bus reset routine which is invoked prior to mdiobus_scan(). Once we have a proper PHY driver/device registered, all workarounds are located there (e.g: power management suspend/resume calls).

Currently, MoCA fixed PHYs are always in link-up state, regardless of whether the link is actually up or not. Add code to properly detect MoCA link state changes and to reflect the new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of detecting MoCA link state changes. The code works as follows: 1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP or UMAC_IRQ_LINK_DOWN interrupt. 2. Link up/down interrupt is processed in bcmgenet_irq_task(), which calls phy_mac_interrupt(). 3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks the PHY state machine. 4. PHY state machine proceeds to read the fixed PHY link status register. 5. When the fixed PHY link status register is being read, the new function bcmgenet_fixed_phy_link_update() gets called. It copies the fixed PHY phydev->link value to the fixed PHY status->link. 6. PHY state machine receives the new link state of the fixed PHY. 7. MoCA fixed PHY link state now correctly reflects the real MoCA hardware link state. Signed-off-by: NPetri Gynther <pgynther@google.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Power up the GPHY while we are bringing-up the network interface, and conversely, upon bring down, power the GPHY down. In order to avoid creating hardware hazards, make sure that the GPHY gets powered on during bcmgenet_open() prior to the UniMAC being reset as the UniMAC may start creating activity towards the GPHY if we reverse the steps.
