Allocating memory can fail, and since we have the memory we need in sky2_resume when sky2_suspend is called, just stop the hardware without freeing the memory it's using. This avoids the possibility of failing because we can't allocate memory in sky2_resume(), and allows sharing code with sky2_restart(). Signed-off-by:

Code to bring down all sky2 interfaces and bring it up again can be reused in sky2_suspend and sky2_resume. Factor the code to bring the interfaces down into sky2_all_down and the up code into sky2_all_up. Signed-off-by:

netif_stop_queue does not ensure all in-progress transmits are complete, so use netif_tx_disable() instead. Secondly, make sure NAPI polls are disabled before stopping the tx queue, otherwise sky2_status_intr might trigger a TX queue wakeup between when we stop the queue and NAPI is disabled.

There appears to be an off-by-1 defect in the maximum packet size copied when copybreak is speified in these modules. The copybreak module params are specified as: "Maximum size of packet that is copied to a new buffer on receive" The tests are changed from "< copybreak" to "<= copybreak" and moved into new static functions for readability.

When adding more than 14 mac-vlan adapters on e1000 the driver would fire a WARN_ON when adding the 15th. The WARN_ON in this case is completely un-necessary, as the code below the WARN_ON is directly handling the value the WARN_ON triggered on. CC: Jiri Pirko <jpirko@redhat.com> Signed-off-by:

This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand. Compile tested x86 allmodconfig only. Signed-off-by: -

We can't use zero magic "bad" value to check if IXGBE_RSC_CB(skb)->dma is valid. It is only valid in x86/arm/m68k/alpha architectures and in spark, powerPC and other architectures it should be ~0. As per Benjamin Herrenschmidt feedback use a bool flag to decide if the packet unmapping is delayed in hardware RSC till EOP is reached Signed-off-by:

i) Fixes a bug where e1000_sw_lcd_config_ich8lan() was calling e1000_lan_init_done_ich8lan() to poll the STATUS.LAN_INIT_DONE bit to make sure the MAC had completed the PHY configuration. However, e1000_lan_init_done_ich8lan() had already been called in one of the two places where PHY reset occurs for ICHx/PCHx parts, which caused the second call to busy-wait for 150 msec because the LAN_INIT_DONE bit had already been checked and cleared. ii) Cleanup the two separate PHY reset code paths, i.e. the full-chip reset in e1000_reset_hw_ich8lan() and the PHY-only reset in e1000_phy_hw_reset_ich8lan(). There was duplicate code in both paths to be performed post-reset that are now combined into one new function - e1000_post_phy_reset_ich8lan(). This cleanup also included moving the clearing of the PHY Reset Asserted bit in the STATUS register (now done for all ICH/PCH parts) and the check for the indication from h/w that basic configuration has completed back to where it previously was in e1000_get_cfg_done_ich8lan(). iii) Corrected a few comments Signed-off-by:

The mac->arc_subsystem was being incorrectly used to flag whether or not manageability was enabled when it should only be used to state whether the ARC (Host interface) subsystem is available on a particular MAC _and_ only valid when any manageability is enabled. The ARC subsystem is currently only available on 80003es2lan and 82573 parts supported by the driver. A new flag, has_fwsm, is introduced to be used when checking if manageability is enabled but only on parts that acutally have an FWSM register. While the above parts have an FWSM register, there are other parts that have FWSM but do not have support for the ARC subsystem, namely 82571/2 and ICHx/PCH. And then there are parts that have manageability, but do not have either FWSM register or support for the ARC subsystem - these are 82574 and 82583. For 80003es2lan, 82571/2/3 and ICH/PCH parts, this patch makes no functional changes, it only corrects the usage of the manageability flags. For 82574 and 82583, it fixes the incorrect accesses of the non-existent FWSM register and ARC subsystem as well as corrects the check for management pass-through. Signed-off-by:

The force_speed_duplex function pointer was incorrectly set. Instead of calling the 82577-specific version it was calling the m88 version which, among other incorrect things, reset the PHY causing autonegotiation to be re-enabled in the PHY resulting in the link defaulting to half-duplex. The 82577-specific force_speed_duplex function also had an issue where it disabled Auto-MDI-X which caused the link to not come up. Signed-off-by:

After every reset all ICH/PCH parts call this function which acquires the swflag, performs a workaround on applicable parts and releases the swflag. There is no reason for parts for which this workaround is not applicable to acquire and release the swflag so the function should just return without doing anything for these parts. This also provides for the indentation of most of the function contents to be shifted left cleaning up the code. Signed-off-by:

In MSI-X mode when an IMPI SoL session was active (i.e. the PHY reset was blocked), the LSC interrupt generated by s/w to start the watchdog which started the transmitter was not getting fired by the hardware because bit 24 (the 'other' cause bit) also needed to be set. Without an active SoL session, the PHY was reset which caused the h/w to fire the LSC interrupt. Signed-off-by:

When running ethtool online diagnostics with no open interface, there is a short period of time where the driver relinquishes control of the adapter during which time AMT (manageability firmware) can put the adapter into an unknown state resulting in such things as link test failure, hardware hang, reporting an incorrect link speed, etc. Resetting the adapter during an open() resolves this by putting the adapter into a quiescent state.
