* [PATCH net-next] net: marvell: fix return type of ndo_start_xmit function
From: YueHaibing @ 2018-09-19 10:19 UTC (permalink / raw)
To: davem, thomas.petazzoni, antoine.tenart, maxime.chevallier,
ymarkman, stefanc, keescook, allen.lkml
Cc: linux-kernel, netdev, YueHaibing
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

FIELD_SIZEOF is defined as a macro to calculate the specified value. Therefore,

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

* [PATCH net-next] net: sun: fix return type of ndo_start_xmit function
From: YueHaibing @ 2018-09-19 11:21 UTC (permalink / raw)
To: davem, shannon.nelson, alexander.h.duyck, yanjun.zhu,
jeffrey.t.kirsher, tklauser
Cc: linux-kernel, netdev, YueHaibing
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.
Found by coccinelle.

FIELD_SIZEOF is defined as a macro to calculate the specified value. Therefore,
We prefer to use the macro rather than calculating its value.

I always thought "GPL2 compatible" was the same as "subset" because of
the restrictions clause of GPL2. But IANAL, so for the avoidance of
doubt I'll take your advice and put both.
