Some comments on Ethernet driver:

MII and RMII interfaces are mutually exclusive and CDL should reflect this. A
cdl_option with legal values "RMII" "MII" would provide it and in addition make
it visible in configtool.


"Remap pins" could be also visible if it were cdl_option.


Regarding pins, some addition to my statement in Comment #11. Since pins are
being provided by HAL, they should be defined in HAL (unlike other Ethernet
definitions such as registers, etc.). Preferable place is plf_io.h rather than
var_io.h. because other chips (present or future) may have different pin
mapping.
On the other hand, the pin functions - once assigned to Ethernet (although pins
are provided provided by HAL) belong to Ethernet so their naming should reflect
this Here is a plf_io.h snuppet:

plf_io.h snippet --------------------------------

#define CYGHWR_IO_ETH_STM32MAC_MII_COL \
        CYGHWR_HAL_STM32_GPIO(A, 3,  IN , FLOATING)
...
-------------------------------------------------

Also if_stm32.c
Could CYGHWR_HAL_STM32_GPIO_SET(CYGHWR_...); lines be replaced by a loop?
And in order to avoid specifying HAL specific macros in a device driver, a new
macro can be defined CYGHWR_IO_ETH_STM32MAC_PIN(...).

Note: In macro names above I arbitrarily put "STM32MAC" segment. Probably there
is a more appropriate name for this Ethernet controller.

CYGNUM_DEVS_ETH_CORTEXM_STM32_RX_BUFS: Is there a range of legal values?
BTW other Ethernet devices that I have seen also provide configuration option
for TX_BUFFS.Is this fixed on STM32 Ethernet controller?


TCP/IP Checksum generation and check.
FYI lwIP is aware of such hardware features
http://sourceware.org/ml/ecos-discuss/2011-07/msg00017.html
and it would be good if they are implemented.
