We've removed kernel option EXT_RESOURCES almost two years ago.

2022-08-18neta: Fix MTU change sequenceKornel Dulęba
The IFF_DRV_RUNNING flag is used to see if the interface needs to be temporarily brought down during MTU change sequence. The problem here is that this flag is cleared in mvneta_stop_locked, resulting in the reinitialization logic never being executed after MTU has been changed. Fix that by saving the flag value before the interface is brought down.

After MTU is updated we might start using allocating RX buffers from different pool. (MJUM9BYTES vs MCLBYTES) Because of that we need to update the RX buffer size in hardware. Previously it was done only when the interface was up, which is incorrect since MTU can be changed at any time.

2020-08-01Fix TX csum handling in if_mvnetaMarcin Wojtas
The mvneta device requires MVNETA_TX_CMD_L4_CHECKSUM_NONE bit to be set in the tx descriptor is checksum not required. However, mvneta_tx_set_csumflag() is not setting this flag currently, causing the hardware to randomly corrupt IP header during transmission. This affects injected IPv4 packets that skips kernel IP stack processing (e.g. DHCP), as well as all IPv6 packets, since the driver currently does not offload csum for IPv6. The fix is to remove all the early return paths from mvneta_tx_set_csumflag() which do not set the MVNETA_TX_CMD_L4_CHECKSUM_NONE flag.

2018-04-08Clean up OF_getprop_alloc APIOleksandr Tymoshenko
OF_getprop_alloc takes element size argument and returns number of elements in the property. There are valid use cases for such behavior but mostly API consumers pass 1 as element size to get string properties. What API users would expect from OF_getprop_alloc is to be a combination of malloc + OF_getprop with the same semantic of return value. This patch modifies API signature to match these expectations. For the valid use cases with element size != 1 and to reduce modification scope new OF_getprop_alloc_multi function has been introduced that behaves the same way OF_getprop_alloc behaved prior to this patch.
