Ben Hutchings	86fc187fcc	sfc: Remove unused definitions of EF10 user-mode DMA descriptors ... These DMA descriptor types will only be used by the userland networking stack.

Jon Cooper	ee45fd92c7	sfc: Use TX PIO for sufficiently small packets ... Sufficiently small linear packets can be copied into the PIO buffer with a single call to memcpy_toio(). Non-linear packets require an intermediate cache-line-sized buffer. [bwh: I wrote the first version of this, but Jon did the hard work to handle non-linear packets.] Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>	2013-09-20 19:31:52 +01:00
Ben Hutchings	9c51716512	sfc: Add EF10 register and structure definitions ... Also update comments and assertions in io.h: - EF10 does not have a general BIU collector and does not have the bug affecting TIMER_COMMAND_REG[0] on Falcon/Siena - The WPTR field moved within RX_DESC_UPD_REG and TX_DESC_UPD_REG. Adjust efx_writed_page() accordingly Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>	2013-08-29 18:12:16 +01:00
