When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. This cleans up a lot of unneeded code and logic around the debugfs files, making all of this much simpler and easier to understand. Cc: Tom Lendacky <thomas.lendacky@amd.com> Cc: "David S.

2019-04-01net: move skb->xmit_more hint to softnet dataFlorian Westphal
There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

2019-01-17amd-xgbe: Fix mdio access for non-zero ports and clause 45 PHYsLendacky, Thomas
The XGBE hardware has support for performing MDIO operations using an MDIO command request. The driver mistakenly uses the mdio port address as the MDIO command request device address instead of the MDIO command request port address. Additionally, the driver does not properly check for and create a clause 45 MDIO command. Check the supplied MDIO register to determine if the request is a clause 45 operation (MII_ADDR_C45). For a clause 45 operation, extract the device address and register number from the supplied MDIO register and use them to set the MDIO command request device address and register number fields. For a clause 22 operation, the MDIO request device address is set to zero and the MDIO command request register number is set to the supplied MDIO register. In either case, the supplied MDIO port address is used as the MDIO command request port address.

2018-06-23net: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing.

2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-05-23amd-xgbe: Improve SFP 100Mbps auto-negotiationTom Lendacky
After changing speed to 100Mbps as a result of auto-negotiation (AN), some 10/100/1000Mbps SFPs indicate a successful link (no faults or loss of signal), but cannot successfully transmit or receive data. These SFPs required an extra auto-negotiation (AN) after the speed change in order to operate properly. Add a quirk for these SFPs so that if the outcome of the AN actually results in changing to a new speed, re-initiate AN at that new speed.
