2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher1-27/+1
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

The ixgbe driver use the compile check to determine if it can send TLPs to Root Port with the Relaxed Ordering Attribute set, this is too inconvenient, now the new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added to the kernel and we could check the bit4 in the PCIe Device Control register to determine whether we should use the Relaxed Ordering Attributes or not, so use this new way in the ixgbe driver.

2016-04-25ixgbe: use BIT() macroJacob Keller1-3/+3
Several areas of ixgbe were written before widespread usage of the BIT(n) macro. With the impending release of GCC 6 and its associated new warnings, some usages such as (1 << 31) have been noted within the ixgbe driver source. Fix these wholesale and prevent future issues by simply using BIT macro instead of hand coded bit shifts. Also fix a few shifts that are shifting values into place by using the 'u' prefix to indicate unsigned. It doesn't strictly matter in these cases because we're not shifting by too large a value, but these are all unsigned values and should be indicated as such.

2016-04-04ixgbe: Place SWFW semaphore in known valid state at probeDon Skidmore1-0/+1
It is possible on some HW that a system reset could occur when we are holding the SWFW semaphore lock. So next time the driver was loaded we would see it incorrectly as locked. This patch will recover from that state by: Attempting to acquire the semaphore and then regardless of whether or not it was acquire we immediately release it. This will force us into a known good state.

This patch adds support for bypassing the VLVF entry creation when the PF is adding a new VLAN.

2013-07-30ixgbe: fix semaphore lock for I2C read/writes on 82598Emil Tantilov1-10/+22
ixgbe_read/write_i2c_phy_82598() does not hold the SWFW_SYNC semaphore for the entire function. Instead the lock is held only during the phy.ops.read/write_reg operations. As result when the function is being called simultaneously the I2C read/writes can be corrupted. The following patch introduces the SWFW_SYNC semaphore for the entire ixgbe_read/write_i2c_phy_82598() function. To accomplish this I had to create 2 separate functions: ixgbe_read_phy_reg_mdi() ixgbe_write_phy_reg_mdi() Those functions are identical to ixgbe_read/write_phy_reg_generic() sans the locking, and can be used in ixgbe_read/write_i2c_phy_82598() with the SWFW_SYNC semaphore being held.

This change updates the link flow control configuration so that we correctly set the link flow control settings for DCB. Previously we would have to call the fc_enable call 8 times, once for each packet buffer. If we move that logic into the fc_enable call itself we can avoid multiple unnecessary register writes. This change also corrects an issue in which we were only shifting the water marks for 82599 parts by 6 instead of 10.
