Subject: [PATCH 01/13] PCI: Add PCI_EXP_DEVCTL_PAYLOAD_* macros
Date: Fri, 1 Oct 2021 21:58:44 +0200 [thread overview]
Message-ID: <20211001195856.10081-2-kabel@kernel.org> (raw)
In-Reply-To: <20211001195856.10081-1-kabel@kernel.org>
From: Pali Rohár <pali@kernel.org>
Define a macro PCI_EXP_DEVCTL_PAYLOAD_* for every possible Max Payload
Size in linux/pci_regs.h, in the same style as PCI_EXP_DEVCTL_READRQ_*.
