CONFIG_DE2104X_DSL: Descriptor Skip Length in 32 bit longwords

General informations

The Linux kernel configuration item CONFIG_DE2104X_DSL has multiple definitions:

Descriptor Skip Length in 32 bit longwords found in drivers/net/ethernet/dec/tulip/Kconfig

The configuration item CONFIG_DE2104X_DSL:

• prompt: Descriptor Skip Length in 32 bit longwords
• type: int
• depends on: CONFIG_DE2104X
• defined in drivers/net/ethernet/dec/tulip/Kconfig
• found in Linux kernels: 3.2–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12, 6.13-rc+HEAD

Help text

Setting this value allows to align ring buffer descriptors into their own cache lines. Value of 4 corresponds to the typical 32 byte line (the descriptor is 16 bytes). This is necessary on systems that lack cache coherence, an example is PowerMac 5500. Otherwise 0 is safe. Default is 0, and range is 0 to 31.
