cregit-Linux how code gets into the kernel

Release 4.11 drivers/net/ethernet/amd/declance.c

/*
 *    Lance ethernet driver for the MIPS processor based
 *      DECstation family
 *
 *
 *      adopted from sunlance.c by Richard van den Berg
 *
 *      Copyright (C) 2002, 2003, 2005, 2006  Maciej W. Rozycki
 *
 *      additional sources:
 *      - PMAD-AA TURBOchannel Ethernet Module Functional Specification,
 *        Revision 1.2
 *
 *      History:
 *
 *      v0.001: The kernel accepts the code and it shows the hardware address.
 *
 *      v0.002: Removed most sparc stuff, left only some module and dma stuff.
 *
 *      v0.003: Enhanced base address calculation from proposals by
 *              Harald Koerfgen and Thomas Riemer.
 *
 *      v0.004: lance-regs is pointing at the right addresses, added prom
 *              check. First start of address mapping and DMA.
 *
 *      v0.005: started to play around with LANCE-DMA. This driver will not
 *              work for non IOASIC lances. HK
 *
 *      v0.006: added pointer arrays to lance_private and setup routine for
 *              them in dec_lance_init. HK
 *
 *      v0.007: Big shit. The LANCE seems to use a different DMA mechanism to
 *              access the init block. This looks like one (short) word at a
 *              time, but the smallest amount the IOASIC can transfer is a
 *              (long) word. So we have a 2-2 padding here. Changed
 *              lance_init_block accordingly. The 16-16 padding for the buffers
 *              seems to be correct. HK
 *
 *      v0.008: mods to make PMAX_LANCE work. 01/09/1999 triemer
 *
 *      v0.009: Module support fixes, multiple interfaces support, various
 *              bits. macro
 *
 *      v0.010: Fixes for the PMAD mapping of the LANCE buffer and for the
 *              PMAX requirement to only use halfword accesses to the
 *              buffer. macro
 *
 *      v0.011: Converted the PMAD to the driver model. macro

 * The DS2100/3100 have a linear 64 kB buffer which supports halfword
 * accesses only.  Each halfword of the buffer is word-aligned in the
 * CPU address space.
 *
 * The PMAD-AA has a 128 kB buffer on-board.
 *
 * The IOASIC LANCE devices use a shared memory region.  This region
 * as seen from the CPU is (max) 128 kB long and has to be on an 128 kB
 * boundary.  The LANCE sees this as a 64 kB long continuous memory
 * region.
 *
 * The LANCE's DMA address is used as an index in this buffer and DMA
 * takes place in bursts of eight 16-bit words which are packed into
 * four 32-bit words by the IOASIC.  This leads to a strange padding:
 * 16 bytes of valid data followed by a 16 byte gap :-(.
