netdev->dev_addr should only be modified via helpers, but someone may be casting off the const. Add a runtime check to catch abuses. Signed-off-by:

There are no module callers in-tree and it's hard to justify why anyone would init or flush addresses of a netdev (note the flush is more of a destructor, it frees netdev->dev_addr). Signed-off-by:

Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. We converted all users to make modifications via appropriate helpers, make netdev->dev_addr const. The update helpers need to upcast from the buffer to struct netdev_hw_addr. Signed-off-by:

Add support for the TI DP83561-SP Gigabit ethernet phy device. The dp83561-sp is a radiation hardened space grade gigabit ethernet PHY. It has been tested for single event latch upto 121 MeV, the critical reliability parameter for space designs. It interfaces directly to twisted pair media through an external transformer. And the device also interfaces directly to the MAC layer through Reduced GMII (RGMII) and MII. DP83867, DP83869 and DP83561-SP, all these parts support 1000Base-T/ 100Base-TX/ and 10Base-Te standards and have similar register map for the core functionality. The data sheet for this part is at https://www.ti.com/product/DP83561-SPSigned-off-by:

do_div() does a 64-by-32 division. Here the divisor is an unsigned long which on some platforms is 64 bit wide. So use div64_ul instead of do_div to avoid a possible truncation. Eliminate the following coccicheck warning: ./drivers/net/ethernet/renesas/ravb_main.c:2492:1-7: WARNING: do_div() does a 64-by-32 division, please consider using div64_ul instead. Reported-by:

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memset(), avoid intentionally writing across neighboring fields. Add struct_group() to mark region of struct stats_reply_data that should be initialized, which can now be done in a single memset() call. Signed-off-by:

Recently pci_read/write_vpd_any() have been added to the PCI VPD API. These functions allow to access VPD address space outside the auto-detected VPD, and they can be used to significantly simplify the eeprom ethtool ops. Tested with a 88E8070 card with 1KB EEPROM. Signed-off-by:

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() in struct nig_stats around members egress_mac_pkt0_lo, egress_mac_pkt0_hi, egress_mac_pkt1_lo, and egress_mac_pkt1_hi (and the respective members in struct bnx2x_eth_stats), so they can be referenced together. This will allow memcpy() and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of struct bnx2x_eth_stats's rx_stat_ifhcinbadoctets_hi. "pahole" shows no size nor member offset changes to either struct. "objdump -d" shows no meaningful object code changes (i.e. only source line number induced differences and optimizations). Additionally adds BUILD_BUG_ON() to compare the separate struct group sizes. Reviewed-by:

We always need an RX queue, and there's no reconfig situation either where we would need to free & rebuild the queue. So allocate the RX queue right from the start, and avoid freeing it during unrelated qeth_free_qdio_queues() calls. Signed-off-by:

With these (and another patch which didn't fit) the build is more or less clean with all cross-compilers available on kernel.org. I say more or less because around half of the arches fail to build for unrelated reasons right now. Most of the changes here are for m68k, 32bit x86 and alpha. ==================== Signed-off-by: -
