When calling 'ifconfig bond0 down' the following happens: bond_close() bond_alb_deinitialize() tlb_deinitialize() kfree(bond_info->tx_hashtbl) bond_info->tx_hashtbl = NULL Unfortunately if there are still slaves in the bond, when removing the module the following happens: bonding_exit() bond_free_all() bond_release_all() bond_alb_deinit_slave() tlb_clear_slave() tx_hash_table = BOND_ALB_INFO(bond).tx_hashtbl u32 next_index = tx_hash_table[index].next As you might guess we panic when trying to access a few entries into the table that no longer exists. I experimented with several options (like moving the calls to tlb_deinitialize somewhere else), but it really makes the most sense to be part of the bond_close routine. It also didn't seem logical move tlb_clear_slave around too much, so the simplest option seems to add a check in tlb_clear_slave to make sure we haven't already wiped the tx_hashtbl away before searching for all the non-existent hash-table entries that used to point to the slave as the output interface.

The TBI is on the MDIO bus with the PHY (sort of) and is accessed via the gianfar's MDIO registers, using the functions gfar_local_mdio_read/write(), which don't do any locking. The previously attached PHY will start a work-queue on a timer, and probably an irq handler as well, which will talk to the PHY and thus use the MDIO bus. This uses phy_read/write(), which have locking, but not against the gfar_local_mdio versions. The result is that PHY code will try to use the MDIO bus at the same time as the SerDes setup code, corrupting the transfers. Setting up the SerDes before attaching to the PHY will insure that there is no race between the SerDes code and *our* PHY, but doesn't fix everything. Typically the PHYs for all gianfar devices are on the same MDIO bus, which is associated with the first gianfar device. This means that the first gianfar's SerDes code could corrupt the MDIO transfers for a different gianfar's PHY. The lock used by phy_read/write() is contained in the mii_bus structure, which is pointed to by the PHY. This is difficult to access from the gianfar drivers, as there is no link between a gianfar device and the mii_bus which shares the same MDIO registers. As far as the device layer and drivers are concerned they are two unrelated devices (which happen to share registers). Generally all gianfar devices' PHYs will be on the bus associated with the first gianfar. But this might not be the case, so simply locking the gianfar's PHY's mii bus might not lock the mii bus that the SerDes setup code is going to use. We solve this by having the code that creates the gianfar platform device look in the device tree for an mdio device that shares the gianfar's registers. If one is found the ID of its platform device is saved in the gianfar's platform data. A new function in the gianfar mii code, gfar_get_miibus(), can use the bus ID to search through the platform devices for a gianfar_mdio device with the right ID. The platform device's driver data is the mii_bus structure, which the SerDes setup code can use to lock the current bus.

As noticed by Saikiran Madugula, commit 7447ef63cf2dfdc444f4c72ae13f604350b2e25f ("loopback: Remove rest of LOOPBACK_TSO code.") got rid of emulate_large_send_offload() but didn't get rid of the call site as well.
